-               <description>&lt;p&gt;A few days ago, I wrote about
-&lt;a href=&quot;http://people.skolelinux.org/pere/blog/The_Thinkpad_is_dead__long_live_the_Thinkpad_X230_.html&quot;&gt;the
-problems I experienced with my new X230 and its SSD disk&lt;/a&gt;, which
-was dying during installation because it is unable to cope with
-sustained write.  My supplier is in contact with
-&lt;a href=&quot;http://www.lenovo.com/&quot;&gt;Lenovo&lt;/a&gt;, and they wanted to send a
-replacement disk to try to fix the problem.  They decided to send an
-identical model, so my hopes for a permanent fix was slim.&lt;/p&gt;
-
-&lt;p&gt;Anyway, today I got the replacement disk and tried to install
-Debian Edu Wheezy with encrypted disk on it.  The new disk have the
-same firmware version as the original.  This time my hope raised
-slightly as the installation progressed, as the original disk used to
-die after 4-7% of the disk was written to, while this time it kept
-going past 10%, 20%, 40% and even past 50%.  But around 60%, the disk
-died again and I was back on square one.  I still do not have a new
-laptop with a disk I can trust.  I can not live with a disk that might
-lock up when I download a new
-&lt;a href=&quot;http://www.skolelinux.org/&quot;&gt;Debian Edu / Skolelinux&lt;/a&gt; ISO or
-other large files.  I look forward to hearing from my supplier with
-the next proposal from Lenovo.&lt;/p&gt;
-
-&lt;p&gt;The original disk is marked Intel SSD 520 Series 180 GB,
-11S0C38722Z1ZNME35X1TR, ISN: CVCV321407HB180EGN, SA: G57560302, FW:

-&lt;p&gt;The replacement disk is marked Intel SSD 520 Series 180 GB,

-
-&lt;p&gt;The only difference is in the first number (serial number?), ISN,
-SA, date and WNPP values.  Mentioning all the details here in case
-someone is able to use the information to find a way to identify the
-failing disk among working ones (if any such working disk actually
-exist).&lt;/p&gt;

-               <description>&lt;p&gt;Half a year ago, I reported that I had to find a
-&lt;a href=&quot;http://people.skolelinux.org/pere/blog/Thank_you_Thinkpad_X41__for_your_long_and_trustworthy_service.html&quot;&gt;replacement
-for my trusty old Thinkpad X41&lt;/a&gt;.  Unfortunately I did not have much
-time to spend on it, and it took a while to find a model I believe
-will do the job, but two days ago the replacement finally arrived.  I
-ended up picking a
-&lt;a href=&quot;http://www.linlap.com/lenovo_thinkpad_x230&quot;&gt;Thinkpad X230&lt;/a&gt;
-with SSD disk (NZDAJMN).  I first test installed Debian Edu Wheezy as
-a roaming workstation, and it seemed to work flawlessly.  But my
-second installation with encrypted disk was not as successful.  More
-on that below.&lt;/p&gt;
-
-&lt;p&gt;I had a hard time trying to track down a good laptop, as my most
-important requirements (robust and with a good keyboard) are never
-listed in the feature list.  But I did get good help from the search
-feature at &lt;a href=&quot;http://www.prisjakt.no/&quot;&gt;Prisjakt&lt;/a&gt;, which
-allowed me to limit the list of interesting laptops based on my other
-requirements.  A bit surprising that SSD disk are not disks according
-to that search interface, so I had to drop specifying the number of
-disks from my search parameters.  I also asked around among friends to
-get their impression on keyboards and robustness.&lt;/p&gt;
-
-&lt;p&gt;So the new laptop arrived, and it is quite a lot wider than the
-X41.  I am not quite convinced about the keyboard, as it is
-significantly wider than my old keyboard, and I have to stretch my
-hand a lot more to reach the edges.  But the key response is fairly
-good and the individual key shape is fairly easy to handle, so I hope
-I will get used to it.  My old X40 was starting to fail, and I really
-needed a new laptop now. :)&lt;/p&gt;
-
-&lt;p&gt;Turning off the touch pad was simple.  All it took was a quick
-visit to the BIOS during boot it disable it.&lt;/p&gt;
-
-&lt;p&gt;But there is a fatal problem with the laptop.  The 180 GB SSD disk
-lock up during load.  And this happen when installing Debian Wheezy
-with encrypted disk, while the disk is being filled with random data.
-I also tested to install Ubuntu Raring, and it happen there too if I
-reenable the code to fill the disk with random data (it is disabled by
-default in Ubuntu).  And the bug with is already known.  It was
-reported to Debian as &lt;a href=&quot;http://bugs.debian.org/691427&quot;&gt;BTS
-report #691427 2012-10-25&lt;/a&gt; (journal commit I/O error on brand-new
-Thinkpad T430s ext4 on lvm on SSD).  It is also reported to the Linux
-kernel developers as
-&lt;a href=&quot;https://bugzilla.kernel.org/show_bug.cgi?id=51861&quot;&gt;Kernel bugzilla
-report #51861 2012-12-20&lt;/a&gt; (Intel SSD 520 stops working under load
-(SSDSC2BW180A3L in Lenovo ThinkPad T430s)). It is also reported on the
-Lenovo forums, both for
-&lt;a href=&quot;http://forums.lenovo.com/t5/T400-T500-and-newer-T-series/T430s-Intel-SSD-520-180GB-issue/m-p/1070549&quot;&gt;T430
-2012-11-10&lt;/a&gt; and for
-&lt;a href=&quot;http://forums.lenovo.com/t5/X-Series-ThinkPad-Laptops/x230-SATA-errors-with-180GB-Intel-520-SSD-under-heavy-write-load/m-p/1068147&quot;&gt;X230
-03-20-2013&lt;/a&gt;.  The problem do not only affect installation.  The
-reports state that the disk lock up during use if many writes are done
-on the disk, so it is much no use to work around the installation
-problem and end up with a computer that can lock up at any moment.
-There is even a
-&lt;a href=&quot;https://git.efficios.com/?p=test-ssd.git&quot;&gt;small C program
-available&lt;/a&gt; that will lock up the hard drive after running a few
-minutes by writing to a file.&lt;/p&gt;
-
-&lt;p&gt;I&#39;ve contacted my supplier and asked how to handle this, and after
-contacting PCHELP Norway (request 01D1FDP) which handle support
-requests for Lenovo, his first suggestion was to upgrade the disk
-firmware.  Unfortunately there is no newer firmware available from
-Lenovo, as my disk already have the most recent one (version LF1i).  I
-hope to hear more from him today and hope the problem can be
-fixed. :)&lt;/p&gt;

-                <pubDate>Wed, 3 Jul 2013 14:00:00 +0200</pubDate>
-               <description>&lt;p&gt;The fourth wheezy based alpha release of Debian Edu was wrapped up
-today.  This is the release announcement:&lt;/p&gt;
-
-&lt;p&gt;&lt;strong&gt;New features for Debian Edu 7.1+edu0~alpha3 released
-2013-07-03&lt;/strong&gt;&lt;/p&gt;
-
-&lt;p&gt;These are the release notes for for Debian Edu / Skolelinux
-7.1+edu0~alpha3, based on Debian with codename &quot;Wheezy&quot;.&lt;/p&gt;
-
-&lt;p&gt;&lt;strong&gt;About Debian Edu and Skolelinux&lt;/strong&gt;&lt;/p&gt;
-
-&lt;p&gt;&lt;a href=&quot;http://www.skolelinux.org/&quot;&gt;Debian Edu, also known as
-Skolelinux&lt;/a&gt;, is a Linux distribution based on Debian providing an
-out-of-the box environment of a completely configured school
-network. Immediately after installation a school server running all
-services needed for a school network is set up just waiting for users
-and machines being added via GOsa², a comfortable Web-UI. A netbooting
-environment is prepared using PXE, so after initial installation of
-the main server from CD, DVD or USB stick all other machines can be
-installed via the network. The provided school server provides LDAP
-database and Kerberos authentication service, centralized home
-directories, DHCP server, web proxy and many other services. The
-desktop contains
-&lt;a href=&quot;http://people.skolelinux.org/pere/blog/Educational_applications_included_in_Debian_Edu___Skolelinux__the_screenshot_collection____.html&quot;&gt;more
-than 60 educational software packages&lt;/a&gt; and more are available from
-the Debian archive, and schools can choose between KDE, Gnome, LXDE
-and Xfce desktop environment.&lt;/p&gt;
-
-&lt;p&gt;This is the fourth test release based on Debian Wheezy. Basically
-this is an updated and slightly improved version compared to the
-Squeeze release.&lt;/p&gt;
-
-&lt;p&gt;&lt;strong&gt;Software updates&lt;/strong&gt;&lt;/p&gt;
-&lt;ul&gt;
-  &lt;li&gt;Dropped ispell dictionaries from our default installation.&lt;/li&gt;
-  &lt;li&gt;Dropped menu-xdg from the KDE desktop option, to drop the Debian
-    submenu.  It was not included with Gnome, LXDE or Xfce, so this
-    brings KDE in line with the others.&lt;/li&gt;
-  &lt;li&gt;Dropped xdrawchem, xjig and xsok from our default installation as
-    they don&#39;t have a desktop menu entry and thus won&#39;t show up in the
-    menu now that menu-xdg was removed.&lt;/li&gt;
-  &lt;li&gt;Removed the killer system to kill left behind processes on
-    multi-user machines, as it was no longer able to understand when a
-    X display was in use and killed the processes of the active users
-    too.&lt;/li&gt;
-  &lt;li&gt;Dropped the golearn (from goplay) package as the debtags in wheezy
-    are too few to make the package useful.&lt;/li&gt;
-&lt;/ul&gt;
-&lt;p&gt;&lt;strong&gt;Other changes&lt;/strong&gt;&lt;/p&gt;
-&lt;ul&gt;
-  &lt;li&gt;Updated artwork matching http://wiki.debian.org/DebianArt/Themes/Joy
-  &lt;li&gt;Multi-arch i386/amd64 USB stick ISO available.&lt;/li&gt;
-  &lt;li&gt;Got rid of ispell/wordlist related debconf questions that showed
-    up for some language options.&lt;/li&gt;
-  &lt;li&gt;Switched to using http.debian.net as APT source by default.&lt;/li&gt;
-  &lt;li&gt;Fixed proxy configuration on Main Server installations.&lt;/li&gt;
-  &lt;li&gt;Changed LTSP setup to ask dpkg to use force-unsafe-io the same way
-    d-i is doing it.&lt;/li&gt;
-  &lt;li&gt;Made sure root and user passwords were not left behind in the
-    debconf database after installation on Main Server installations.&lt;/li&gt;
-  &lt;li&gt;Made Roaming Workstation dynamic setup more robust and added draft
-    script setup-ad-client to hook a Roaming Workstation up to a
-    Active Directory server instead of a Debian Edu Main Server.&lt;/li&gt;
-  &lt;li&gt;Update system to install needed firmware packages during
-    installation, to work properly in Wheezy.&lt;/li&gt;
-  &lt;li&gt;Update system to handle hardware quirks (debian-edu-hwsetup).&lt;/li&gt;
-  &lt;li&gt;Corrected PXE installation setup to properly pass selected desktop
-    and keymap settings to PXE installation clients.&lt;/li&gt;
-  &lt;li&gt;LTSP diskless workstations use sshfs by default, allowing them to
-    work without adding them to DNS and NIS netgroups for NFS access.&lt;/li&gt;
-&lt;/ul&gt;
-&lt;p&gt;&lt;strong&gt;Known issues&lt;/strong&gt;&lt;/p&gt;
-&lt;ul&gt;
-  &lt;li&gt;No mass import of user account data in GOsa (ldif or csv)
-    available yet (698840).&lt;/li&gt;
-  &lt;li&gt;Artwork not enabled for all desktops.&lt;/li&gt;
-&lt;/ul&gt;
-&lt;p&gt;&lt;strong&gt;Where to get it&lt;/strong&gt;&lt;/p&gt;

-               <description>&lt;p&gt;It annoys me when the computer fail to do automatically what it is
-perfectly capable of, and I have to do it manually to get things
-working.  One such task is to find out what firmware packages are
-needed to get the hardware on my computer working.  Most often this
-affect the wifi card, but some times it even affect the RAID
-controller or the ethernet card.  Today I pushed version 0.4 of the
-&lt;a href=&quot;http://packages.qa.debian.org/isenkram&quot;&gt;Isenkram package&lt;/a&gt;
-including a new script isenkram-autoinstall-firmware handling the

+               <description>&lt;p&gt;For a while now, I have been looking for a sensible offsite backup
+solution for use at home.  My requirements are simple, it must be
+cheap and locally encrypted (in other words, I keep the encryption
+keys, the storage provider do not have access to my private files).
+One idea me and my friends had many years ago, before the cloud
+storage providers showed up, was to use Google mail as storage,
+writing a Linux block device storing blocks as emails in the mail
+service provided by Google, and thus get heaps of free space.  On top
+of this one can add encryption, RAID and volume management to have
+lots of (fairly slow, I admit that) cheap and encrypted storage.  But
+I never found time to implement such system.  But the last few weeks I
+have looked at a system called
+&lt;a href=&quot;https://bitbucket.org/nikratio/s3ql/&quot;&gt;S3QL&lt;/a&gt;, a locally
+mounted network backed file system with the features I need.&lt;/p&gt;
+
+&lt;p&gt;S3QL is a fuse file system with a local cache and cloud storage,
+handling several different storage providers, any with Amazon S3,
+Google Drive or OpenStack API.  There are heaps of such storage
+providers.  S3QL can also use a local directory as storage, which
+combined with sshfs allow for file storage on any ssh server.  S3QL
+include support for encryption, compression, de-duplication, snapshots
+and immutable file systems, allowing me to mount the remote storage as
+a local mount point, look at and use the files as if they were local,
+while the content is stored in the cloud as well.  This allow me to
+have a backup that should survive fire.  The file system can not be
+shared between several machines at the same time, as only one can
+mount it at the time, but any machine with the encryption key and
+access to the storage service can mount it if it is unmounted.&lt;/p&gt;
+
+&lt;p&gt;It is simple to use.  I&#39;m using it on Debian Wheezy, where the
+package is included already.  So to get started, run &lt;tt&gt;apt-get
+install s3ql&lt;/tt&gt;.  Next, pick a storage provider.  I ended up picking
+Greenqloud, after reading their nice recipe on
+&lt;a href=&quot;https://greenqloud.zendesk.com/entries/44611757-How-To-Use-S3QL-to-mount-a-StorageQloud-bucket-on-Debian-Wheezy&quot;&gt;how
+to use S3QL with their Amazon S3 service&lt;/a&gt;, because I trust the laws
+in Iceland more than those in USA when it come to keeping my personal
+data safe and private, and thus would rather spend money on a company
+in Iceland.  Another nice recipe is available from the article
+&lt;a href=&quot;http://www.admin-magazine.com/HPC/Articles/HPC-Cloud-Storage&quot;&gt;S3QL
+Filesystem for HPC Storage&lt;/a&gt; by Jeff Layton in the HPC section of
+Admin magazine.  When the provider is picked, figure out how to get
+the API key needed to connect to the storage API.  With Greencloud,
+the key did not show up until I had added payment details to my
+account.&lt;/p&gt;
+
+&lt;p&gt;Armed with the API access details, it is time to create the file
+system.  First, create a new bucket in the cloud.  This bucket is the
+file system storage area.  I picked a bucket name reflecting the
+machine that was going to store data there, but any name will do.
+I&#39;ll refer to it as &lt;tt&gt;bucket-name&lt;/tt&gt; below.  In addition, one need
+the API login and password, and a locally created password.  Store it
+all in ~root/.s3ql/authinfo2 like this:
+
+&lt;p&gt;&lt;blockquote&gt;&lt;pre&gt;
+[s3c]
+storage-url: s3c://s.greenqloud.com:443/bucket-name
+backend-login: API-login
+backend-password: API-password
+fs-passphrase: local-password
+&lt;/pre&gt;&lt;/blockquote&gt;&lt;/p&gt;
+
+&lt;p&gt;I create my local passphrase using &lt;tt&gt;pwget 50&lt;/tt&gt; or similar,
+but any sensible way to create a fairly random password should do it.
+Armed with these details, it is now time to run mkfs, entering the API
+details and password to create it:&lt;/p&gt;
+
+&lt;p&gt;&lt;blockquote&gt;&lt;pre&gt;
+# mkdir -m 700 /var/lib/s3ql-cache
+# mkfs.s3ql --cachedir /var/lib/s3ql-cache --authfile /root/.s3ql/authinfo2 \
+  --ssl s3c://s.greenqloud.com:443/bucket-name
+Enter backend login: 
+Enter backend password: 
+Before using S3QL, make sure to read the user&#39;s guide, especially
+the &#39;Important Rules to Avoid Loosing Data&#39; section.
+Enter encryption password:

+# &lt;/pre&gt;&lt;/blockquote&gt;&lt;/p&gt;
+
+&lt;p&gt;The next step is mounting the file system to make the storage available.
+
+&lt;p&gt;&lt;blockquote&gt;&lt;pre&gt;
+# mount.s3ql --cachedir /var/lib/s3ql-cache --authfile /root/.s3ql/authinfo2 \
+  --ssl --allow-root s3c://s.greenqloud.com:443/bucket-name /s3ql

+#
+&lt;/pre&gt;&lt;/blockquote&gt;&lt;/p&gt;
+
+&lt;p&gt;The file system is now ready for use.  I use rsync to store my
+backups in it, and as the metadata used by rsync is downloaded at
+mount time, no network traffic (and storage cost) is triggered by
+running rsync.  To unmount, one should not use the normal umount
+command, as this will not flush the cache to the cloud storage, but
+instead running the umount.s3ql command like this:
+
+&lt;p&gt;&lt;blockquote&gt;&lt;pre&gt;
+# umount.s3ql /s3ql

 # 
 # 

-&lt;/pre&gt;&lt;/p&gt;
-
-&lt;p&gt;When all the requested firmware is present, a simple message is
-printed instead:&lt;/p&gt;
-
-&lt;p&gt;&lt;pre&gt;
-# isenkram-autoinstall-firmware 
-info: did not find any firmware files requested by loaded kernel modules.  exiting
+&lt;/pre&gt;&lt;/blockquote&gt;&lt;/p&gt;
+
+&lt;p&gt;There is a fsck command available to check the file system and
+correct any problems detected.  This can be used if the local server
+crashes while the file system is mounted, to reset the &quot;already
+mounted&quot; flag.  This is what it look like when processing a working
+file system:&lt;/p&gt;
+
+&lt;p&gt;&lt;blockquote&gt;&lt;pre&gt;

-&lt;p&gt;It could use some polish, but it is already working well and saving
-me some time when setting up new machines. :)&lt;/p&gt;
-
-&lt;p&gt;So, how does it work?  It look at the set of currently loaded
-kernel modules, and look up each one of them using modinfo, to find
-the firmware files listed in the module meta-information.  Next, it
-download the Contents file from a nearby APT mirror, and search for
-the firmware files in this file to locate the package with the
-requested firmware file.  If the package is in the non-free section, a
-non-free APT source is added and the package is installed using
-&lt;tt&gt;apt-get install&lt;/tt&gt;.  The end result is a slightly better working
-machine.&lt;/p&gt;
-
-&lt;p&gt;I hope someone find time to implement a more polished version of
-this script as part of the hw-detect debian-installer module, to
-finally fix &lt;a href=&quot;http://bugs.debian.org/655507&quot;&gt;BTS report
-#655507&lt;/a&gt;.  There really is no need to insert USB sticks with
-firmware during a PXE install when the packages already are available
-from the nearby Debian mirror.&lt;/p&gt;

-               <description>&lt;p&gt;In the &lt;a href=&quot;http://www.skolelinux.org/&quot;&gt;Debian Edu /
-Skolelinux&lt;/a&gt; project, we include a post-installation test suite,
-which check that services are running, working, and return the
-expected results.  It runs automatically just after the first boot on
-test installations (using test ISOs), but not on production
-installations (using non-test ISOs).  It test that the LDAP service is
-operating, Kerberos is responding, DNS is replying, file systems are
-online resizable, etc, etc.  And it check that the PXE service is
-configured, which is the topic of this post.&lt;/p&gt;
-
-&lt;p&gt;The last week I&#39;ve fixed the DVD and USB stick ISOs for our Debian
-Edu Wheezy release.  These ISOs are supposed to be able to install a
-complete system without any Internet connection, but for that to
-happen all the needed packages need to be on them.  Thanks to our test
-suite, I discovered that we had forgotten to adjust our PXE setup to
-cope with the new names and paths used by the netboot d-i packages.
-When Internet connectivity was available, the installer fall back to
-using wget to fetch d-i boot images, but when offline it require
-working packages to get it working.  And ad the packages changed name
-from debian-installer-6.0-netboot-$arch to
-debian-installer-7.0-netboot-$arch, we no longer pulled in the
-packages during installation.  Without our test suite, I suspect we
-would never have discovered this before release.  Now it is fixed
-right after we got the ISOs operational.&lt;/p&gt;
-
-&lt;p&gt;Another by-product of the test suite is that we can ask system
-administrators with problems getting Debian Edu to work, to run the
-test suite using &lt;tt&gt;/usr/sbin/debian-edu-test-install&lt;/tt&gt; and see if
-any errors are detected.  This usually pinpoint the subsystem causing
-the problem.&lt;/p&gt;
-
-&lt;p&gt;If you want to help us help kids learn how to share and create,
-please join us on
-&lt;a href=&quot;irc://irc.debian.org/%23debian-edu&quot;&gt;#debian-edu on
-irc.debian.org&lt;/a&gt; and the
-&lt;a href=&quot;http://lists.debian.org/debian-edu/&quot;&gt;debian-edu@&lt;/a&gt; mailing
-list.&lt;/p&gt;
+&lt;/pre&gt;&lt;/blockquote&gt;&lt;/p&gt;
+
+&lt;p&gt;Thanks to the cache, working on files that fit in the cache is very
+quick, about the same speed as local file access.  Uploading large
+amount of data is to me limited by the bandwidth out of and into my
+house.  Uploading 685 MiB with a 100 MiB cache gave me 305 kiB/s,
+which is very close to my upload speed, and downloading the same
+Debian installation ISO gave me 610 kiB/s, close to my download speed.
+Both were measured using &lt;tt&gt;dd&lt;/tt&gt;.  So for me, the bottleneck is my
+network, not the file system code.  I do not know what a good cache
+size would be, but suspect that the cache should e larger than your
+working set.&lt;/p&gt;
+
+&lt;p&gt;I mentioned that only one machine can mount the file system at the
+time.  If another machine try, it is told that the file system is
+busy:&lt;/p&gt;
+
+&lt;p&gt;&lt;blockquote&gt;&lt;pre&gt;
+# mount.s3ql --cachedir /var/lib/s3ql-cache --authfile /root/.s3ql/authinfo2 \
+  --ssl --allow-root s3c://s.greenqloud.com:443/bucket-name /s3ql
+Using 8 upload threads.
+Backend reports that fs is still mounted elsewhere, aborting.
+#
+&lt;/pre&gt;&lt;/blockquote&gt;&lt;/p&gt;
+
+&lt;p&gt;The file content is uploaded when the cache is full, while the
+metadata is uploaded once every 24 hour by default.  To ensure the
+file system content is flushed to the cloud, one can either umount the
+file system, or ask S3QL to flush the cache and metadata using
+s3qlctrl:
+
+&lt;p&gt;&lt;blockquote&gt;&lt;pre&gt;
+# s3qlctrl upload-meta /s3ql
+# s3qlctrl flushcache /s3ql
+# 
+&lt;/pre&gt;&lt;/blockquote&gt;&lt;/p&gt;
+
+&lt;p&gt;If you are curious about how much space your data uses in the
+cloud, and how much compression and deduplication cut down on the
+storage usage, you can use s3qlstat on the mounted file system to get
+a report:&lt;/p&gt;
+
+&lt;p&gt;&lt;blockquote&gt;&lt;pre&gt;
+# s3qlstat /s3ql
+Directory entries:    9141
+Inodes:               9143
+Data blocks:          8851
+Total data size:      22049.38 MB
+After de-duplication: 21955.46 MB (99.57% of total)
+After compression:    21877.28 MB (99.22% of total, 99.64% of de-duplicated)
+Database size:        2.39 MB (uncompressed)
+(some values do not take into account not-yet-uploaded dirty blocks in cache)
+#
+&lt;/pre&gt;&lt;/blockquote&gt;&lt;/p&gt;
+
+&lt;p&gt;I mentioned earlier that there are several possible suppliers of
+storage.  I did not try to locate them all, but am aware of at least
+&lt;a href=&quot;https://www.greenqloud.com/&quot;&gt;Greenqloud&lt;/a&gt;,
+&lt;a href=&quot;http://drive.google.com/&quot;&gt;Google Drive&lt;/a&gt;,
+&lt;a href=&quot;http://aws.amazon.com/s3/&quot;&gt;Amazon S3 web serivces&lt;/a&gt;,
+&lt;a href=&quot;http://www.rackspace.com/&quot;&gt;Rackspace&lt;/a&gt; and
+&lt;a href=&quot;http://crowncloud.net/&quot;&gt;Crowncloud&lt;/A&gt;.  The latter even
+accept payment in Bitcoin.  Pick one that suit your need.  Some of
+them provide several GiB of free storage, but the prize models are
+quite different and you will have to figure out what suits you
+best.&lt;/p&gt;
+
+&lt;p&gt;While researching this blog post, I had a look at research papers
+and posters discussing the S3QL file system.  There are several, which
+told me that the file system is getting a critical check by the
+science community and increased my confidence in using it.  One nice
+poster is titled
+&quot;&lt;a href=&quot;http://www.lanl.gov/orgs/adtsc/publications/science_highlights_2013/docs/pg68_69.pdf&quot;&gt;An
+Innovative Parallel Cloud Storage System using OpenStack’s SwiftObject
+Store and Transformative Parallel I/O Approach&lt;/a&gt;&quot; by Hsing-Bung
+Chen, Benjamin McClelland, David Sherrill, Alfred Torrez, Parks Fields
+and Pamela Smith.  Please  have a look.&lt;/p&gt;
+
+&lt;p&gt;Given my problems with different file systems earlier, I decided to
+check out the mounted S3QL file system to see if it would be usable as
+a home directory (in other word, that it provided POSIX semantics when
+it come to locking and umask handling etc).  Running
+&lt;a href=&quot;http://people.skolelinux.org/pere/blog/Testing_if_a_file_system_can_be_used_for_home_directories___.html&quot;&gt;my
+test code to check file system semantics&lt;/a&gt;, I was happy to discover that
+no error was found.  So the file system can be used for home
+directories, if one chooses to do so.&lt;/p&gt;
+
+&lt;p&gt;If you do not want a locally file system, and want something that
+work without the Linux fuse file system, I would like to mention the
+&lt;a href=&quot;http://www.tarsnap.com/&quot;&gt;Tarsnap service&lt;/a&gt;, which also
+provide locally encrypted backup using a command line client.  It have
+a nicer access control system, where one can split out read and write
+access, allowing some systems to write to the backup and others to
+only read from it.&lt;/p&gt;
+
+&lt;p&gt;As usual, if you use Bitcoin and want to show your support of my
+activities, please send Bitcoin donations to my address
+&lt;b&gt;&lt;a href=&quot;bitcoin:15oWEoG9dUPovwmUL9KWAnYRtNJEkP1u1b&amp;label=PetterReinholdtsenBlog&quot;&gt;15oWEoG9dUPovwmUL9KWAnYRtNJEkP1u1b&lt;/a&gt;&lt;/b&gt;.&lt;/p&gt;

-Skolelinux&lt;/a&gt; distribution have users and contributors all around the
-globe.  And a while back, an enterprising young man showed up on
-&lt;a href=&quot;irc://irc.debian.org/%23debian-edu&quot;&gt;our IRC channel
-#debian-edu&lt;/a&gt; and started asking questions about how Debian Edu
-worked.  We answered as good as we could, and even convinced him to
-help us with translations.  And today I managed to get an interview
-with him, to learn more about him.&lt;/p&gt;
-
-&lt;p&gt;&lt;strong&gt;Who are you, and how do you spend your days?&lt;/strong&gt;&lt;/p&gt;
-
-&lt;p&gt;I&#39;m a 25 year old free software enthusiast, living in Romania,
-which is also my country of origin. Back in 2009, at a New Year&#39;s Eve
-party, I had a very nice &lt;strike&gt;beer&lt;/strike&gt; discussion with a
-friend, when we realized we have no organised Debian community in our
-country. A few days later, we put together the infrastructure for such
-community and even gathered a nice Debian-ish crowd. Since then, I
-began my quest as a free software hacker and activist and I am
-constantly trying to cover as much ground as possible on that
-field.&lt;/p&gt;
-
-&lt;p&gt;A few years ago I founded a small web development company, which
-provided me the flexible schedule I needed so much for my
-activities. For the last 13 months, I have been the Technical Director
-of &lt;a href=&quot;http://ceata.org/&quot;&gt;Fundația Ceata&lt;/a&gt;, which is a free
-software activist organisation endorsed by the FSF and the FSFE, and
-the only one we have in our country.&lt;/p&gt;
-
-&lt;p&gt;&lt;strong&gt;How did you get in contact with the Skolelinux / Debian Edu
-project?&lt;/strong&gt;&lt;/p&gt;

+               <description>&lt;p&gt;I dag kom endelig avgjørelsen fra EU-domstolen om
+datalagringsdirektivet, som ikke overraskende ble dømt ulovlig og i
+strid med borgernes grunnleggende rettigheter.  Hvis du lurer på hva
+datalagringsdirektivet er for noe, så er det
+&lt;a href=&quot;http://tv.nrk.no/program/koid75005313/tema-dine-digitale-spor-datalagringsdirektivet&quot;&gt;en

-&lt;p&gt;The idea of participating in the Debian Edu project was a surprise
-even to me, since I never used it before I began getting involved in
-it. This year I had a great opportunity to deliver a talk on
-educational software, and I knew immediately where to look. It was a
-love at first sight, since I was previously involved with some of the
-technologies the project incorporates, and I rapidly found a lot of
-ways to contribute.&lt;/p&gt;
-
-&lt;p&gt;My first contributions consisted in translating the installer and
-configuration dialogs, then I found some bugs to squash (I still
-haven&#39;t fixed them yet though), and I even got my eyes on some other
-areas where I can prove myself helpful. Since the appetite for free
-software in my country is pretty low, I&#39;ll be happy to be the first
-one around here advocating for the project&#39;s adoption in educational
-environments, and maybe even get my hands dirty in creating a flavour
-for our own needs. I am not used to make very advanced plannings, so
-from now on, time will tell what I&#39;ll be doing next, but I think I
-have a pretty consistent starting point.&lt;/p&gt;
-
-&lt;p&gt;&lt;strong&gt;What do you see as the advantages of Skolelinux/Debian
-Edu?&lt;/strong&gt;&lt;/p&gt;
+&lt;p&gt;Her er et liten knippe nyhetsoppslag om saken, og jeg regner med at
+det kommer flere ut over dagen.  Flere kan finnes
+&lt;a href=&quot;http://www.mylder.no/?drill=datalagringsdirektivet&amp;intern=1&quot;&gt;via
+mylder&lt;/a&gt;.&lt;/p&gt;

 
 

-&lt;p&gt;Not a long time ago, I was in the position of configuring and
-maintaining a LDAP server on some Debian derivative, and I must say it
-took me a while. A long time ago, I was maintaining a bigger
-Samba-powered infrastructure, and I must say I spent quite a lot of
-time on it. I have similar stories about many of the services included
-with Skolelinux, and the main advantage I see about it is the
-out-of-the box availability of them, making it quite competitive when
-it comes to managing a school&#39;s network, for example.&lt;/p&gt;
-
-&lt;p&gt;Of course, there is more to say about Skolelinux than the
-availability of the software included, its flexibility in various
-scenarios is something I can&#39;t wait to experiment &quot;into the wild&quot; (I
-only played with virtual machines so far). And I am sure there is a
-lot more I haven&#39;t discovered yet about it, being so new within the
-project.&lt;/p&gt;
+&lt;p&gt;&lt;ul&gt;

 
 

-&lt;p&gt;&lt;strong&gt;What do you see as the disadvantages of Skolelinux / Debian
-Edu?&lt;/strong&gt;&lt;/p&gt;
+&lt;li&gt;&lt;a href=&quot;http://e24.no/digital/eu-domstolen-datalagringsdirektivet-er-ugyldig/22879592&quot;&gt;EU-domstolen:
+Datalagringsdirektivet er ugyldig&lt;/a&gt; - e24.no 2014-04-08

 
 

-&lt;p&gt;As usual, when it comes to Debian Blends, I see as the biggest
-disadvantage the lack of a numerous team dedicated to the
-project. Every day I see the same names in the changelogs, and I have
-a constantly fear of the bus factor in this story.  I&#39;d like to see
-Debian Edu advertised more as an entry point into the Debian
-ecosystem, especially amongst newcomers and students. IMHO there are a
-lot low-hanging fruits in terms of bug squashing, and enough
-opportunities to get the feeling of the Debian Project&#39;s dynamics. Not
-to mention it&#39;s a very fun blend to work on!&lt;/p&gt;
-
-&lt;p&gt;Derived from the previous statement, is the delay in catching up
-with the main Debian release and documentation. This is common though
-to all blends and derivatives, but it&#39;s an issue we can all work
-on.&lt;/p&gt;

-&lt;p&gt;I can hardly imagine myself spending a day without Vim, since my
-daily routine covers writing code and hacking configuration files. I
-am a fan of the Awesome window manager (but I also like the
-Enlightenment project a lot!),
-&lt;a href=&quot;http://www.claws-mail.org/‎&quot;&gt;Claws Mail&lt;/a&gt; due to its ease of
-use and very configurable behaviour. Recently I fell in love with
-&lt;a href=&quot;https://launchpad.net/redshift&quot;&gt;Redshift&lt;/a&gt;, which helps me
-get through the night without headaches. Of course, there is much more
-stuff in this bag, but I&#39;ll need a blog on my own for doing this!&lt;/p&gt;

-&lt;p&gt;&lt;strong&gt;Which strategy do you believe is the right one to use to
-get schools to use free software?&lt;/strong&gt;&lt;/p&gt;
-
-&lt;p&gt;Well, on this field, I cannot do much more than experiment right
-now. So, being far from having a recipe for success, I can only assume
-that:&lt;/p&gt;
+&lt;li&gt;&lt;a href=&quot;http://www.nrk.no/norge/_-datalagringsdirektivet-er-ugyldig-1.11655929&quot;&gt;EU-domstolen:
+– Datalagringsdirektivet er ugyldig&lt;/a&gt; - nrk.no 2014-04-08&lt;/li&gt;

+Datalagringsdirektivet er ugyldig&lt;/a&gt; - vg.no 2014-04-08&lt;/li&gt;

 
 

-&lt;li&gt;schools would like to get rid of proprietary software&lt;/li&gt;
+&lt;li&gt;&lt;a href=&quot;http://www.dagbladet.no/2014/04/08/nyheter/innenriks/datalagringsdirektivet/personvern/32711646/&quot;&gt;-
+Vi bør skrote hele datalagringsdirektivet&lt;/a&gt; - dagbladet.no
+2014-04-08&lt;/li&gt;

 
 

-&lt;li&gt;students will love the openness of the system, and will want to
-    experiment with it - maybe we need to harvest the native curiosity
-    of teenagers more?&lt;/li&gt;
+&lt;li&gt;&lt;a href=&quot;http://www.digi.no/928137/eu-domstolen-dld-er-ugyldig&quot;&gt;EU-domstolen:
+DLD er ugyldig&lt;/a&gt; - digi.no 2014-04-08&lt;/li&gt;

 
 

-&lt;li&gt;there is no &quot;right one&quot; when it comes to strategies, but it would
-    be useful to have some success stories published somewhere, so
-    other can get some inspiration from them (I know I&#39;d promote
-    them!)&lt;/li&gt;

+court declares data retention directive invalid&lt;/a&gt; - irishtimes.com
+2014-04-08&lt;/li&gt;

 
 

-&lt;li&gt;more active promotion - talks, conferences, even small school
-    lectures can do magical things if they encounter at least one
-    person interested. Who knows who that person might be? ;-)&lt;/li&gt;
+&lt;li&gt;&lt;a href=&quot;http://www.reuters.com/article/2014/04/08/us-eu-data-ruling-idUSBREA370F020140408?feedType=RSS&quot;&gt;EU

+reuters.com 2014-04-08&lt;/li&gt;

 
 &lt;/ul&gt;
 
 &lt;/ul&gt;

-
-&lt;p&gt;I also see some problems in getting Skolelinux into schools; for
-example, in our country we have a great deal of corruption issues, so
-it might be hard(er) to fight against proprietary solutions. Also,
-people who relied on commercial software for all their lives, would be
-very hard to convert against their will.&lt;/p&gt;
+&lt;/p&gt;
+
+&lt;p&gt;Jeg synes det er veldig fint at nok en stemme slår fast at
+totalitær overvåkning av befolkningen er uakseptabelt, men det er
+fortsatt like viktig å beskytte privatsfæren som før, da de
+teknologiske mulighetene fortsatt finnes og utnyttes, og jeg tror
+innsats i prosjekter som
+&lt;a href=&quot;https://wiki.debian.org/FreedomBox&quot;&gt;Freedombox&lt;/a&gt; og
+&lt;a href=&quot;http://www.dugnadsnett.no/&quot;&gt;Dugnadsnett&lt;/a&gt; er viktigere enn
+noen gang.&lt;/p&gt;
+
+&lt;p&gt;&lt;strong&gt;Update 2014-04-08 12:10&lt;/strong&gt;: Kronerullingen for å

+               <description>&lt;p&gt;Microsoft have announced that Windows XP reaches its end of life
+2014-04-08, in 7 days.  But there are heaps of machines still running
+Windows XP, and depending on Windows XP to run their applications, and
+upgrading will be expensive, both when it comes to money and when it
+comes to the amount of effort needed to migrate from Windows XP to a
+new operating system.  Some obvious options (buy new a Windows
+machine, buy a MacOSX machine, install Linux on the existing machine)
+are already well known and covered elsewhere.  Most of them involve
+leaving the user applications installed on Windows XP behind and
+trying out replacements or updated versions. In this blog post I want
+to mention one strange bird that allow people to keep the hardware and
+the existing Windows XP applications and run them on a free software
+operating system that is Windows XP compatible.&lt;/p&gt;
+
+&lt;p&gt;&lt;a href=&quot;http://www.reactos.org/&quot;&gt;ReactOS&lt;/a&gt; is a free software
+operating system (GNU GPL licensed) working on providing a operating
+system that is binary compatible with Windows, able to run windows
+programs directly and to use Windows drivers for hardware directly.
+The project goal is for Windows user to keep their existing machines,
+drivers and software, and gain the advantages from user a operating
+system without usage limitations caused by non-free licensing.  It is
+a Windows clone running directly on the hardware, so quite different
+from the approach taken by &lt;a href=&quot;http://www.winehq.org/&quot;&gt;the Wine
+project&lt;/a&gt;, which make it possible to run Windows binaries on
+Linux.&lt;/p&gt;
+
+&lt;p&gt;The ReactOS project share code with the Wine project, so most
+shared libraries available on Windows are already implemented already.
+There is also a software manager like the one we are used to on Linux,
+allowing the user to install free software applications with a simple
+click directly from the Internet.  Check out the
+&lt;a href=&quot;http://www.reactos.org/screenshots&quot;&gt;screen shots on the
+project web site&lt;/a&gt; for an idea what it look like (it looks just like
+Windows before metro).&lt;/p&gt;
+
+&lt;p&gt;I do not use ReactOS myself, preferring Linux and Unix like
+operating systems.  I&#39;ve tested it, and it work fine in a virt-manager
+virtual machine.  The browser, minesweeper, notepad etc is working
+fine as far as I can tell.  Unfortunately, my main test application
+is the software included on a CD with the Lego Mindstorms NXT, which
+seem to install just fine from CD but fail to leave any binaries on
+the disk after the installation.  So no luck with that test software.
+No idea why, but hope someone else figure out and fix the problem.
+I&#39;ve tried the ReactOS Live ISO on a physical machine, and it seemed
+to work just fine.  If you like Windows and want to keep running your
+old Windows binaries, check it out by
+&lt;a href=&quot;http://www.reactos.org/download&quot;&gt;downloading&lt;/a&gt; the
+installation CD, the live CD or the preinstalled virtual machine
+image.&lt;/p&gt;

-               <description>&lt;p&gt;There is a certain cross-over between the
-&lt;a href=&quot;http://www.skolelinux.org/&quot;&gt;Debian Edu / Skolelinux
-project&lt;/a&gt; and &lt;a href=&quot;http://www.edubuntu.org/&quot;&gt;the Edubuntu
-project&lt;/a&gt;, and for example the LTSP packages in Debian are a joint
-effort between the projects.  One person with a foot in both camps is
-Jonathan Carter, which I am now happy to present to you.&lt;/p&gt;

+               <description>&lt;p&gt;&lt;a href=&quot;http://www.skolelinux.org/&quot;&gt;Debian Edu / Skolelinux&lt;/a&gt;
+keep gaining new users.  Some weeks ago, a person showed up on IRC,
+&lt;a href=&quot;irc://irc.debian.org/#debian-edu&quot;&gt;#debian-edu&lt;/a&gt;, with a
+wish to contribute, and I managed to get a interview with this great
+contributor Roger Marsal to learn more about his background.&lt;/p&gt;

 
 &lt;p&gt;&lt;strong&gt;Who are you, and how do you spend your days?&lt;/strong&gt;&lt;/p&gt;
 
 
 &lt;p&gt;&lt;strong&gt;Who are you, and how do you spend your days?&lt;/strong&gt;&lt;/p&gt;
 

-&lt;p&gt;I&#39;m a South-African free software geek who lives in Cape Town. My
-days vary quite a bit since I&#39;m involved in too many things. As I&#39;m
-getting older I&#39;m learning how to focus a bit more :)&lt;/p&gt;
+&lt;p&gt;My name is Roger Marsal, I&#39;m 27 years old (1986 generation) and I
+live in Barcelona, Spain. I&#39;ve got a strong business background and I
+work as a patrimony manager and as a real estate agent.  Additionally,
+I&#39;ve co-founded a British based tech company that is nowadays on the
+last development phase of a new social networking concept.&lt;/p&gt;
+
+&lt;p&gt;I&#39;m a Linux enthusiast that started its journey with Ubuntu four years
+ago and have recently switched to Debian seeking rock solid stability
+and as a necessary step to gain expertise.&lt;/p&gt;

 
 

-&lt;p&gt;I&#39;m also an Edubuntu contributor and I love when there are
-opportunities for the Edubuntu and Debian Edu projects to benefit from
-each other.&lt;/p&gt;
+&lt;p&gt;In a nutshell, I spend my days working and learning as much as I
+can to face both my job, entrepreneur project and feed my Linux
+hunger.&lt;/p&gt;

 
 &lt;p&gt;&lt;strong&gt;How did you get in contact with the Skolelinux / Debian Edu
 project?&lt;/strong&gt;&lt;/p&gt;
 
 
 &lt;p&gt;&lt;strong&gt;How did you get in contact with the Skolelinux / Debian Edu
 project?&lt;/strong&gt;&lt;/p&gt;
 

-&lt;p&gt;I&#39;ve been somewhat familiar with the project before, but I think my
-first direct exposure to the project was when I met Petter
-[Reinholdtsen] and Knut [Yrvin] at the Edubuntu summit in 2005 in
-London. They provided great feedback that helped the bootstrapping of
-Edubuntu. Back then Edubuntu (and even Ubuntu) was still very new and
-it was great getting input from people who have been around longer. I
-was also still very excitable and said yes to everything and to this
-day I have a big todo list backlog that I&#39;m catching up with. I think
-over the years the relationship between Edubuntu and Debian-Edu has
-been gradually improving, although I think there&#39;s a lot that we could
-still improve on in terms of working together on packages. I&#39;m sure
-we&#39;ll get there one day.&lt;/p&gt;
+&lt;p&gt;I discovered the &lt;a href=&quot;http://www.ltsp.org/&quot;&gt;LTSP&lt;/a&gt; advantages
+with &quot;Ubuntu 12.04 alternate install&quot; and after a year of use I
+started looking for an alternative.  Even though I highly value and
+respect the Ubuntu project, I thought it was necessary for me to
+change to a more robust and stable alternative.  As far as I was using
+Debian on my personal laptop I thought it would be fine to install
+Debian and configure an LTSP server myself.  Surprised, I discovered
+that the Debian project also supported a kind of Edubuntu equivalent,
+and after having some pain I obtained a Debian Edu network up and
+running.  I just loved it.&lt;/p&gt;

 
 &lt;p&gt;&lt;strong&gt;What do you see as the advantages of Skolelinux / Debian
 Edu?&lt;/strong&gt;&lt;/p&gt;
 
 
 &lt;p&gt;&lt;strong&gt;What do you see as the advantages of Skolelinux / Debian
 Edu?&lt;/strong&gt;&lt;/p&gt;
 

-&lt;p&gt;Debian itself already has so many advantages. I could go on about
-it for pages, but in essence I love that it&#39;s a very honest project
-that puts its users first with no hidden agendas and also produces
-very high quality work.&lt;/p&gt;
-
-&lt;p&gt;I think the advantage of Debian Edu is that it makes many common
-set-up tasks simpler so that administrators can get up and running
-with a lot less effort and frustration. At the same time I think it
-helps to standardise installations in schools so that it&#39;s easier for
-community members and commercial suppliers to support.&lt;/p&gt;
+&lt;p&gt;I found a main advantage in that, once you know &quot;the tips and
+tricks&quot;, a new installation just works out of the box. It&#39;s the most
+complete alternative I&#39;ve found to create an LTSP network. All the
+other distributions seems to be made of plastic, Debian Edu seems to
+be made of steel.&lt;/p&gt;

 
 &lt;p&gt;&lt;strong&gt;What do you see as the disadvantages of Skolelinux / Debian
 Edu?&lt;/strong&gt;&lt;/p&gt;
 
 
 &lt;p&gt;&lt;strong&gt;What do you see as the disadvantages of Skolelinux / Debian
 Edu?&lt;/strong&gt;&lt;/p&gt;
 

-&lt;p&gt;I had to re-type this one a few times because I&#39;m trying to
-separate &quot;disadvantages&quot; from &quot;areas that need improvement&quot; (which is
-what I originally rambled on about)&lt;/p&gt;
-
-&lt;p&gt;The biggest disadvantage I can think of is lack of manpower. The
-project could do so much more if there were more good contributors. I
-think some of the problems are external too. Free software and free
-content in education is a no-brainer but it takes some time to catch
-on. When you&#39;ve been working with the same proprietary eco-system for
-years and have gotten used to it, it can be hard to adjust to some
-concepts in the free software world. It would be nice if there were
-more Debian Edu consultants across the world. I&#39;d love to be one
-myself but I&#39;m already so over-committed that it&#39;s just not possible
-currently.&lt;/p&gt;
-
-&lt;p&gt;I think the best short-term solution to that large-scale problem is
-for schools to be pro-active and share their experiences and grow
-their skills in-house. I&#39;m often saddened to see how much money
-educational institutions spend on 3rd party solutions that they don&#39;t
-have access to after the service has ended and they could&#39;ve gotten so
-much more value otherwise by being more self-sustainable and
-autonomous.&lt;/p&gt;
+&lt;p&gt;I found two main disadvantages.&lt;/p&gt;
+
+&lt;p&gt;I&#39;m not an expert but I&#39;ve got notions and I had to spent a considerable
+amount of time trying to bring up a standard network topology. I&#39;m quite
+stubborn and I just worked until I did but I&#39;m sure many people with few
+resources (not big schools, but academies for example) would have switched
+or dropped.&lt;/p&gt;
+
+&lt;p&gt;It&#39;s amazing how such a complex system like Debian Edu has achieved
+this out-of-the-box state. Even though tweaking without breaking gets
+more difficult, as more factors have to be considered. This can
+discourage many people too.&lt;/p&gt;

 
 &lt;p&gt;&lt;strong&gt;Which free software do you use daily?&lt;/strong&gt;&lt;/p&gt;
 
 
 &lt;p&gt;&lt;strong&gt;Which free software do you use daily?&lt;/strong&gt;&lt;/p&gt;
 

-&lt;p&gt;My main laptop dual-boots between Debian and Windows 7. I was
-Windows free for years but started dual-booting again last year for
-some games which help me focus and relax (Starcraft II in
-particular). Gaming support on Linux is improving in leaps and bounds
-so I suppose I&#39;ll soon be able to regain that disk space :)&lt;/p&gt;
-
-&lt;p&gt;Besides that I rely on Icedove, Chromium, Terminator, Byobu, irssi,
-git, Tomboy, KVM, VLC and LibreOffice. Recently I&#39;ve been torn on
-which desktop environment I like and I&#39;m taking some refuge in Xfce
-while I figure that out. I like tools that keep things simple. I enjoy
-Python and shell scripting. I went to an Arduino workshop recently and
-it was awesome seeing how easy and simple the IDE software was to get
-up and running in Debian compared to the users running Windows and OS
-X.&lt;/p&gt;
-
-&lt;p&gt;I also use mc which some people frown upon slightly. I got used to
-using Norton Commander in the early 90&#39;s and it stuck (I think the
-people who sneer at it is just jealous that they don&#39;t know how to use
-it :p)
+&lt;p&gt;I use Debian, Firefox, Okular, Inkscape, LibreOffice and
+Virtualbox.&lt;/p&gt;
+

 
 &lt;p&gt;&lt;strong&gt;Which strategy do you believe is the right one to use to
 get schools to use free software?&lt;/strong&gt;&lt;/p&gt;
 
 
 &lt;p&gt;&lt;strong&gt;Which strategy do you believe is the right one to use to
 get schools to use free software?&lt;/strong&gt;&lt;/p&gt;
 

-&lt;p&gt;I think trying to force it is unproductive. I also think that in
-many cases it&#39;s appropriate for schools to use non-free systems and I
-don&#39;t think that there&#39;s any particular moral or ethical problem with
-that.&lt;/p&gt;
-
-&lt;p&gt;I do think though that free software can already solve so so many
-problems in educational institutions and it&#39;s just a shame not taking
-advantage of that.&lt;/p&gt;
-
-&lt;p&gt;I also think that some curricula need serious review. For example,
-some areas of the world rely heavily on very specific versions of MS
-Office, teaching students to parrot menu items instead of learning the
-general concepts. I think that&#39;s very unproductive because firstly, MS
-Office&#39;s interface changes drastically every few years and on top of
-that it also locks in a generation to a product that might not be the
-best solution for them.&lt;/p&gt;
-
-&lt;p&gt;To answer your question, I believe that the right strategy is to
-educate and inform, giving someone the information they require to
-make a decision that would work for them.&lt;/p&gt;
+&lt;p&gt;I don&#39;t think there is a need for a particular strategy. The free
+attribute in both &quot;freedom&quot; and &quot;no price&quot; meanings is what will
+really bring free software to schools. In my experience I can think of
+the &lt;a href=&quot;http://www.r-project.org/&quot;&gt;&quot;R&quot; statistical language&lt;/a&gt;; a
+few years a ago was an extremely nerd tool for university people.
+Today it&#39;s being increasingly used to teach statistics at many
+different level of studies.  I believe free and open software will
+increasingly gain popularity, but I&#39;m sure schools will be one of the
+first scenarios where this will happen.&lt;/p&gt;

+               <description>&lt;p&gt;&lt;a href=&quot;http://www.nuug.no/&quot;&gt;Foreningen NUUG&lt;/a&gt; melder i natt at
+NRK nå har bestemt seg for
+&lt;a href=&quot;http://www.nuug.no/news/NRK_viser_filmen_om_Datalagringsdirektivet_f_rste_gang_2014_03_31.shtml&quot;&gt;når
+den norske dokumentarfilmen om datalagringsdirektivet skal
+sendes&lt;/a&gt; (se &lt;a href=&quot;http://www.imdb.com/title/tt2832844/&quot;&gt;IMDB&lt;/a&gt;
+for detaljer om filmen) . Første visning blir på NRK2 mandag
+2014-03-31 kl. 19:50, og deretter visninger onsdag 2014-04-02
+kl. 12:30, fredag 2014-04-04 kl. 19:40 og søndag 2014-04-06 kl. 15:10.
+Jeg har sett dokumentaren, og jeg anbefaler enhver å se den selv.  Som
+oppvarming mens vi venter anbefaler jeg Bjørn Stærks kronikk i
+Aftenposten fra i går,
+&lt;a href=&quot;http://www.aftenposten.no/meninger/kronikker/Autoritar-gjokunge-7514915.html&quot;&gt;Autoritær
+gjøkunge&lt;/a&gt;, der han gir en grei skisse av hvor ille det står til med
+retten til privatliv og beskyttelsen av demokrati i Norge og resten
+verden, og helt riktig slår fast at det er vi i databransjen som
+sitter med nøkkelen til å gjøre noe med dette.  Jeg har involvert meg
+i prosjektene &lt;a href=&quot;http://www.dugnadsnett.no/&quot;&gt;dugnadsnett.no&lt;/a&gt;
+og &lt;a href=&quot;https://wiki.debian.org/FreedomBox&quot;&gt;FreedomBox&lt;/a&gt; for å
+forsøke å gjøre litt selv for å bedre situasjonen, men det er mye
+hardt arbeid fra mange flere enn meg som gjenstår før vi kan sies å ha
+gjenopprettet balansen.&lt;/p&gt;
+
+&lt;p&gt;Jeg regner med at nettutgaven dukker opp på
+&lt;a href=&quot;http://tv.nrk.no/program/koid75005313/tema-dine-digitale-spor-datalagringsdirektivet&quot;&gt;NRKs
+side om filmen om datalagringsdirektivet&lt;/a&gt; om fem dager.  Hold et
+øye med siden, og tips venner og slekt om at de også bør se den.&lt;/p&gt;

-               <description>&lt;p&gt;When installing RedHat, Fedora, Debian and Ubuntu on some machines,
-the screen just turn black when Linux boot, either during installation
-or on first boot from the hard disk.  I&#39;ve seen it once in a while the
-last few years, but only recently understood the cause.  I&#39;ve seen it
-on HP laptops, and on my latest acquaintance the Packard Bell laptop.
-The reason seem to be in the wiring of some laptops.  The system to
-control the screen background light is inverted, so when Linux try to
-turn the brightness fully on, it end up turning it off instead.  I do
-not know which Linux drivers are affected, but this post is about the
-i915 driver used by the
-&lt;a href=&quot;http://www.linlap.com/packard_bell_easynote_lv&quot;&gt;Packard Bell
-EasyNote LV&lt;/a&gt;, Thinkpad X40 and many other laptops.&lt;/p&gt;
-
-&lt;p&gt;The problem can be worked around two ways.  Either by adding
-i915.invert_brightness=1 as a kernel option, or by adding a file in
-/etc/modprobe.d/ to tell modprobe to add the invert_brightness=1
-option when it load the i915 kernel module.  On Debian and Ubuntu, it
-can be done by running these commands as root:&lt;/p&gt;

+               <guid isPermaLink="true">http://people.skolelinux.org/pere/blog/Public_Trusted_Timestamping_services_for_everyone.html</guid>

+               <description>&lt;p&gt;Did you ever need to store logs or other files in a way that would
+allow it to be used as evidence in court, and needed a way to
+demonstrate without reasonable doubt that the file had not been
+changed since it was created?  Or, did you ever need to document that
+a given document was received at some point in time, like some
+archived document or the answer to an exam, and not changed after it
+was received?  The problem in these settings is to remove the need to
+trust yourself and your computers, while still being able to prove
+that a file is the same as it was at some given time in the past.&lt;/p&gt;
+
+&lt;p&gt;A solution to these problems is to have a trusted third party
+&quot;stamp&quot; the document and verify that at some given time the document
+looked a given way.  Such
+&lt;a href=&quot;https://en.wikipedia.org/wiki/Notarius&quot;&gt;notarius&lt;/a&gt; service
+have been around for thousands of years, and its digital equivalent is
+called a
+&lt;a href=&quot;http://en.wikipedia.org/wiki/Trusted_timestamping&quot;&gt;trusted
+timestamping service&lt;/a&gt;.  &lt;a href=&quot;http://www.ietf.org/&quot;&gt;The Internet
+Engineering Task Force&lt;/a&gt; standardised how such service could work a
+few years ago as &lt;a href=&quot;http://tools.ietf.org/html/rfc3161&quot;&gt;RFC
+3161&lt;/a&gt;.  The mechanism is simple.  Create a hash of the file in
+question, send it to a trusted third party which add a time stamp to
+the hash and sign the result with its private key, and send back the
+signed hash + timestamp.  Both email, FTP and HTTP can be used to
+request such signature, depending on what is provided by the service
+used. Anyone with the document and the signature can then verify that
+the document matches the signature by creating their own hash and
+checking the signature using the trusted third party public key.
+There are several commercial services around providing such
+timestamping.  A quick search for
+&quot;&lt;a href=&quot;https://duckduckgo.com/?q=rfc+3161+service&quot;&gt;rfc 3161
+service&lt;/a&gt;&quot; pointed me to at least
+&lt;a href=&quot;https://www.digistamp.com/technical/how-a-digital-time-stamp-works/&quot;&gt;DigiStamp&lt;/a&gt;,
+&lt;a href=&quot;http://www.quovadisglobal.co.uk/CertificateServices/SigningServices/TimeStamp.aspx&quot;&gt;Quo
+Vadis&lt;/a&gt;,
+&lt;a href=&quot;https://www.globalsign.com/timestamp-service/&quot;&gt;Global Sign&lt;/a&gt;
+and &lt;a href=&quot;http://www.globaltrustfinder.com/TSADefault.aspx&quot;&gt;Global
+Trust Finder&lt;/a&gt;.  The system work as long as the private key of the
+trusted third party is not compromised.&lt;/p&gt;
+
+&lt;p&gt;But as far as I can tell, there are very few public trusted
+timestamp services available for everyone.  I&#39;ve been looking for one
+for a while now. But yesterday I found one over at
+&lt;a href=&quot;https://www.pki.dfn.de/zeitstempeldienst/&quot;&gt;Deutches
+Forschungsnetz&lt;/a&gt; mentioned in
+&lt;a href=&quot;http://www.d-mueller.de/blog/dealing-with-trusted-timestamps-in-php-rfc-3161/&quot;&gt;a
+blog by David Müller&lt;/a&gt;.  I then found
+&lt;a href=&quot;http://www.rz.uni-greifswald.de/support/dfn-pki-zertifikate/zeitstempeldienst.html&quot;&gt;a
+good recipe on how to use the service&lt;/a&gt; over at the University of
+Greifswald.&lt;/p&gt;
+
+&lt;p&gt;&lt;a href=&quot;http://www.openssl.org/&quot;&gt;The OpenSSL library&lt;/a&gt; contain
+both server and tools to use and set up your own signing service.  See
+the ts(1SSL), tsget(1SSL) manual pages for more details.  The
+following shell script demonstrate how to extract a signed timestamp
+for any file on the disk in a Debian environment:&lt;/p&gt;
+
+&lt;p&gt;&lt;blockquote&gt;&lt;pre&gt;
+#!/bin/sh
+set -e
+url=&quot;http://zeitstempel.dfn.de&quot;
+caurl=&quot;https://pki.pca.dfn.de/global-services-ca/pub/cacert/chain.txt&quot;
+reqfile=$(mktemp -t tmp.XXXXXXXXXX.tsq)
+resfile=$(mktemp -t tmp.XXXXXXXXXX.tsr)
+cafile=chain.txt
+if [ ! -f $cafile ] ; then
+    wget -O $cafile &quot;$caurl&quot;
+fi
+openssl ts -query -data &quot;$1&quot; -cert | tee &quot;$reqfile&quot; \
+    | /usr/lib/ssl/misc/tsget -h &quot;$url&quot; -o &quot;$resfile&quot;
+openssl ts -reply -in &quot;$resfile&quot; -text 1&gt;&amp;2
+openssl ts -verify -data &quot;$1&quot; -in &quot;$resfile&quot; -CAfile &quot;$cafile&quot; 1&gt;&amp;2
+base64 &lt; &quot;$resfile&quot;
+rm &quot;$reqfile&quot; &quot;$resfile&quot;
+&lt;/pre&gt;&lt;/blockquote&gt;&lt;/p&gt;
+
+&lt;p&gt;The argument to the script is the file to timestamp, and the output
+is a base64 encoded version of the signature to STDOUT and details
+about the signature to STDERR.  Note that due to
+&lt;a href=&quot;http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=742553&quot;&gt;a bug
+in the tsget script&lt;/a&gt;, you might need to modify the included script
+and remove the last line.  Or just write your own HTTP uploader using
+curl. :) Now you too can prove and verify that files have not been
+changed.&lt;/p&gt;
+
+&lt;p&gt;But the Internet need more public trusted timestamp services.
+Perhaps something for &lt;a href=&quot;http://www.uninett.no/&quot;&gt;Uninett&lt;/a&gt; or
+my work place the &lt;a href=&quot;http://www.uio.no/&quot;&gt;University of Oslo&lt;/a&gt;
+to set up?&lt;/p&gt;

+               <description>&lt;p&gt;Keeping your DVD collection safe from scratches and curious
+children fingers while still having it available when you want to see a
+movie is not straight forward.  My preferred method at the moment is
+to store a full copy of the ISO on a hard drive, and use VLC, Popcorn
+Hour or other useful players to view the resulting file.  This way the
+subtitles and bonus material are still available and using the ISO is
+just like inserting the original DVD record in the DVD player.&lt;/p&gt;
+
+&lt;p&gt;Earlier I used dd for taking security copies, but it do not handle
+DVDs giving read errors (which are quite a few of them).  I&#39;ve also
+tried using
+&lt;a href=&quot;http://people.skolelinux.org/pere/blog/Ripping_problematic_DVDs_using_dvdbackup_and_genisoimage.html&quot;&gt;dvdbackup
+and genisoimage&lt;/a&gt;, but these days I use the marvellous python library
+and program
+&lt;a href=&quot;http://bblank.thinkmo.de/blog/new-software-python-dvdvideo&quot;&gt;python-dvdvideo&lt;/a&gt;
+written by Bastian Blank.  It is
+&lt;a href=&quot;http://packages.qa.debian.org/p/python-dvdvideo.html&quot;&gt;in Debian
+already&lt;/a&gt; and the binary package name is python3-dvdvideo. Instead
+of trying to read every block from the DVD, it parses the file
+structure and figure out which block on the DVD is actually in used,
+and only read those blocks from the DVD.  This work surprisingly well,
+and I have been able to almost backup my entire DVD collection using
+this method.&lt;/p&gt;
+
+&lt;p&gt;So far, python-dvdvideo have failed on between 10 and
+20 DVDs, which is a small fraction of my collection.  The most common
+problem is
+&lt;a href=&quot;https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=720831&quot;&gt;DVDs
+using UTF-16 instead of UTF-8 characters&lt;/a&gt;, which according to
+Bastian is against the DVD specification (and seem to cause some
+players to fail too).  A rarer problem is what seem to be inconsistent
+DVD structures, as the python library
+&lt;a href=&quot;https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=723079&quot;&gt;claim
+there is a overlap between objects&lt;/a&gt;.  An equally rare problem claim
+&lt;a href=&quot;https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=741878&quot;&gt;some
+value is out of range&lt;/a&gt;.  No idea what is going on there.  I wish I
+knew enough about the DVD format to fix these, to ensure my movie
+collection will stay with me in the future.&lt;/p&gt;
+
+&lt;p&gt;So, if you need to keep your DVDs safe, back them up using
+python-dvdvideo. :)&lt;/p&gt;

+               <link>http://people.skolelinux.org/pere/blog/Norsk_utgave_av_Alaveteli___WhatDoTheyKnow_p__trappene.html</link>
+               <guid isPermaLink="true">http://people.skolelinux.org/pere/blog/Norsk_utgave_av_Alaveteli___WhatDoTheyKnow_p__trappene.html</guid>

+               <description>&lt;p&gt;Det offentlige Norge har mye kunnskap og informasjon.  Men hvordan
+kan en få tilgang til den på en enkel måte?  Takket være et lite
+knippe lover og tilhørende forskrifter, blant annet
+&lt;a href=&quot;http://lovdata.no/dokument/NL/lov/2006-05-19-16&quot;&gt;offentlighetsloven&lt;/a&gt;,
+&lt;a href=&quot;http://lovdata.no/dokument/NL/lov/2003-05-09-31&quot;&gt;miljøinformasjonsloven&lt;/a&gt;
+og
+&lt;a href=&quot;http://lovdata.no/dokument/NL/lov/1967-02-10/&quot;&gt;forvaltningsloven&lt;/a&gt;
+har en rett til å spørre det offentlige og få svar.  Men det finnes
+intet offentlig arkiv over hva andre har spurt om, og dermed risikerer en
+å måtte forstyrre myndighetene gang på gang for å få tak i samme
+informasjonen på nytt.  &lt;a href=&quot;http://www.mysociety.org/&quot;&gt;Britiske
+mySociety&lt;/a&gt; har laget tjenesten
+&lt;a href=&quot;http://www.whatdotheyknow.com/&quot;&gt;WhatDoTheyKnow&lt;/a&gt; som gjør
+noe med dette.  I Storbritannia blir WhatdoTheyKnow brukt i
+&lt;a href=&quot;http://www.mysociety.org/2011/07/01/whatdotheyknows-share-of-central-government-foi-requests-q2-2011/&quot;&gt;ca
+15% av alle innsynsforespørsler mot sentraladministrasjonen&lt;/a&gt;.
+Prosjektet heter &lt;a href=&quot;http://www.alaveteli.org/&quot;&gt;Alaveteli&lt;/A&gt;, og
+er takk i bruk en rekke steder etter at løsningen ble generalisert og
+gjort mulig å oversette.  Den hjelper borgerne med å be om innsyn,
+rådgir ved purringer og klager og lar alle se hvilke henvendelser som
+er sendt til det offentlige og hvilke svar som er kommet inn, i et
+søkpart arkiv.  Her i Norge holder vi i foreningen NUUG på å få opp en
+norsk utgave av Alaveteli, og her trenger vi din hjelp med
+oversettelsen.&lt;/p&gt;
+
+&lt;p&gt;Så langt er 76 % av Alaveteli oversatt til norsk bokmål, men vi
+skulle gjerne vært oppe i 100 % før lansering.  Oversettelsen gjøres
+på &lt;a href=&quot;https://www.transifex.com/projects/p/alaveteli/&quot;&gt;Transifex,
+der enhver som registrerer seg&lt;/a&gt; og ber om tilgang til
+bokmålsoversettelsen får bidra.  Vi har satt opp en test av tjenesten
+(som ikke sender epost til det offentlige, kun til oss som holder på å
+sette opp tjenesten) på maskinen
+&lt;a href=&quot;http://alaveteli-dev.nuug.no/&quot;&gt;alaveteli-dev.nuug.no&lt;/a&gt;, der
+en kan se hvordan de oversatte meldingen blir seende ut på nettsiden.
+Når tjenesten lanseres vil den hete
+&lt;a href=&quot;https://www.mimesbrønn.no/&quot;&gt;Mimes brønn&lt;/a&gt;, etter
+visdomskilden som Odin måtte gi øyet sitt for å få drikke i.  Den
+nettsiden er er ennå ikke klar til bruk.&lt;/p&gt;
+
+&lt;p&gt;Hvis noen vil oversette til nynorsk også, så skal vi finne ut
+hvordan vi lager en flerspråklig tjeneste.  Men i første omgang er
+fokus på bokmålsoversettelsen, der vi selv har nok peiling til å ha
+fått oversatt 76%, men trenger hjelp for å komme helt i mål. :)&lt;/p&gt;

+               <description>&lt;p&gt;The &lt;a href=&quot;https://wiki.debian.org/FreedomBox&quot;&gt;Freedombox
+project&lt;/a&gt; is working on providing the software and hardware for
+making it easy for non-technical people to host their data and
+communication at home, and being able to communicate with their
+friends and family encrypted and away from prying eyes.  It has been
+going on for a while, and is slowly progressing towards a new test
+release (0.2).&lt;/p&gt;
+
+&lt;p&gt;And what day could be better than the Pi day to announce that the
+new version will provide &quot;hard drive&quot; / SD card / USB stick images for
+Dreamplug, Raspberry Pi and VirtualBox (or any other virtualization
+system), and can also be installed using a Debian installer preseed
+file.  The Debian based Freedombox is now based on Debian Jessie,
+where most of the needed packages used are already present.  Only one,
+the freedombox-setup package, is missing.  To try to build your own
+boot image to test the current status, fetch the freedom-maker scripts
+and build using
+&lt;a href=&quot;http://packages.qa.debian.org/vmdebootstrap&quot;&gt;vmdebootstrap&lt;/a&gt;
+with a user with sudo access to become root:
+
+&lt;pre&gt;
+git clone http://anonscm.debian.org/git/freedombox/freedom-maker.git \
+  freedom-maker
+sudo apt-get install git vmdebootstrap mercurial python-docutils \
+  mktorrent extlinux virtualbox qemu-user-static binfmt-support \
+  u-boot-tools
+make -C freedom-maker dreamplug-image raspberry-image virtualbox-image
+&lt;/pre&gt;
+
+&lt;p&gt;Root access is needed to run debootstrap and mount loopback
+devices.  See the README for more details on the build. If you do not
+want all three images, trim the make line.  But note that thanks to &lt;a
+href=&quot;https://bugs.debian.org/741407&quot;&gt;a race condition in
+vmdebootstrap&lt;/a&gt;, the build might fail without the patch to the
+kpartx call.&lt;/p&gt;
+
+&lt;p&gt;If you instead want to install using a Debian CD and the preseed
+method, boot a Debian Wheezy ISO and use this boot argument to load
+the preseed values:&lt;/p&gt;

 
 &lt;pre&gt;
 
 &lt;pre&gt;

-mechanism in the Linux kernel&lt;/a&gt; to tell the i915 driver which
-hardware have this problem, and get the driver to invert the
-brightness setting automatically.  To use it, one need to add a row in
-&lt;a href=&quot;http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/tree/drivers/gpu/drm/i915/intel_display.c&quot;&gt;the

-&lt;tt&gt;drivers/gpu/drm/i915/intel_display.c&lt;/tt&gt; (look for &quot;&lt;tt&gt;static

-number (vendor number 8086 is assumed) and subdevice vendor and device
-number.&lt;/p&gt;

-&lt;/pre&gt;&lt;/p&gt;
-
-&lt;p&gt;The resulting intel_quirks entry would then look like this:&lt;/p&gt;
-
-&lt;p&gt;&lt;pre&gt;
-struct intel_quirk intel_quirks[] = {
-       ...
-        /* Packard Bell EasyNote LV11HC needs invert brightness quirk */
-       { 0x0156, 0x1025, 0x0688, quirk_invert_brightness },
-       ...
-}
-&lt;/pre&gt;&lt;/p&gt;
-
-&lt;p&gt;According to the kernel module instructions (as seen using
-&lt;tt&gt;modinfo i915&lt;/tt&gt;), information about hardware needing the
-invert_brightness flag should be sent to the
-&lt;a href=&quot;http://lists.freedesktop.org/mailman/listinfo/dri-devel&quot;&gt;dri-devel
-(at) lists.freedesktop.org&lt;/a&gt; mailing list to reach the kernel
-developers.  But my email about the laptop sent 2013-06-03 have not
-yet shown up in
-&lt;a href=&quot;http://lists.freedesktop.org/archives/dri-devel/2013-June/thread.html&quot;&gt;the
-web archive for the mailing list&lt;/a&gt;, so I suspect they do not accept
-emails from non-subscribers.  Because of this, I sent my patch also to
-the Debian bug tracking system instead as
-&lt;a href=&quot;http://bugs.debian.org/710938&quot;&gt;BTS report #710938&lt;/a&gt;, to make
-sure the patch is not lost.&lt;/p&gt;
-
-&lt;p&gt;Unfortunately, it is not enough to fix the kernel to get Laptops
-with this problem working properly with Linux.  If you use Gnome, your
-worries should be over at this point.  But if you use KDE, there is
-something in KDE ignoring the invert_brightness setting and turning on
-the screen during login.  I&#39;ve reported it to Debian as
-&lt;a href=&quot;http://bugs.debian.org/711237&quot;&gt;BTS report #711237&lt;/a&gt;, and
-have no idea yet how to figure out exactly what subsystem is doing
-this.  Perhaps you can help?  Perhaps you know what the Gnome
-developers did to handle this, and this can give a clue to the KDE
-developers?  Or you know where in KDE the screen brightness is changed
-during login?  If so, please update the BTS report (or get in touch if
-you do not know how to update BTS).&lt;/p&gt;
+&lt;p&gt;But note that due to &lt;a href=&quot;https://bugs.debian.org/740673&quot;&gt;a
+recently introduced bug in apt in Jessie&lt;/a&gt;, the installer will
+currently hang while setting up APT sources.  Killing the
+&#39;&lt;tt&gt;apt-cdrom ident&lt;/tt&gt;&#39; process when it hang a few times during the
+installation will get the installation going.  This affect all
+installations in Jessie, and I expect it will be fixed soon.&lt;/p&gt;
+
+&lt;p&gt;Give it a go and let us know how it goes on the mailing list, and help
+us get the new release published. :) Please join us on
+&lt;a href=&quot;irc://irc.debian.org:6667/%23freedombox&quot;&gt;IRC (#freedombox on
+irc.debian.org)&lt;/a&gt; and
+&lt;a href=&quot;http://lists.alioth.debian.org/mailman/listinfo/freedombox-discuss&quot;&gt;the
+mailing list&lt;/a&gt; if you want to help make this vision come true.&lt;/p&gt;

+               <description>&lt;p&gt;On larger sites, it is useful to use a dedicated storage server for
+storing user home directories and data.  The design for handling this
+in &lt;a href=&quot;http://www.skolelinux.org/&quot;&gt;Debian Edu / Skolelinux&lt;/a&gt;, is
+to update the automount rules in LDAP and let the automount daemon on
+the clients take care of the rest.  I was reminded about the need to
+document this better when one of the customers of
+&lt;a href=&quot;http://www.slxdrift.no/&quot;&gt;Skolelinux Drift AS&lt;/a&gt;, where I am
+on the board of directors, asked about how to do this.  The steps to
+get this working are the following:&lt;/p&gt;
+
+&lt;p&gt;&lt;ol&gt;
+
+&lt;li&gt;Add new storage server in DNS.  I use nas-server.intern as the
+example host here.&lt;/li&gt;
+
+&lt;li&gt;Add automoun LDAP information about this server in LDAP, to allow
+all clients to automatically mount it on reqeust.&lt;/li&gt;
+
+&lt;li&gt;Add the relevant entries in tjener.intern:/etc/fstab, because
+tjener.intern do not use automount to avoid mounting loops.&lt;/li&gt;
+
+&lt;/ol&gt;&lt;/p&gt;
+
+&lt;p&gt;DNS entries are added in GOsa², and not described here.  Follow the
+&lt;a href=&quot;https://wiki.debian.org/DebianEdu/Documentation/Wheezy/GettingStarted&quot;&gt;instructions
+in the manual&lt;/a&gt; (Machine Management with GOsa² in section Getting
+started).&lt;/p&gt;
+
+&lt;p&gt;Ensure that the NFS export points on the server are exported to the
+relevant subnets or machines:&lt;/p&gt;
+
+&lt;p&gt;&lt;blockquote&gt;&lt;pre&gt;
+root@tjener:~# showmount -e nas-server
+Export list for nas-server:
+/storage         10.0.0.0/8
+root@tjener:~#
+&lt;/pre&gt;&lt;/blockquote&gt;&lt;/p&gt;
+
+&lt;p&gt;Here everything on the backbone network is granted access to the
+/storage export.  With NFSv3 it is slightly better to limit it to
+netgroup membership or single IP addresses to have some limits on the
+NFS access.&lt;/p&gt;
+
+&lt;p&gt;The next step is to update LDAP.  This can not be done using GOsa²,
+because it lack a module for automount.  Instead, use ldapvi and add
+the required LDAP objects using an editor.&lt;/p&gt;
+
+&lt;p&gt;&lt;blockquote&gt;&lt;pre&gt;
+ldapvi --ldap-conf -ZD &#39;(cn=admin)&#39; -b ou=automount,dc=skole,dc=skolelinux,dc=no
+&lt;/pre&gt;&lt;/blockquote&gt;&lt;/p&gt;
+
+&lt;p&gt;When the editor show up, add the following LDAP objects at the
+bottom of the document.  The &quot;/&amp;&quot; part in the last LDAP object is a
+wild card matching everything the nas-server exports, removing the
+need to list individual mount points in LDAP.&lt;/p&gt;
+
+&lt;p&gt;&lt;blockquote&gt;&lt;pre&gt;
+add cn=nas-server,ou=auto.skole,ou=automount,dc=skole,dc=skolelinux,dc=no
+objectClass: automount
+cn: nas-server
+automountInformation: -fstype=autofs --timeout=60 ldap:ou=auto.nas-server,ou=automount,dc=skole,dc=skolelinux,dc=no
+
+add ou=auto.nas-server,ou=automount,dc=skole,dc=skolelinux,dc=no
+objectClass: top
+objectClass: automountMap
+ou: auto.nas-server
+
+add cn=/,ou=auto.nas-server,ou=automount,dc=skole,dc=skolelinux,dc=no
+objectClass: automount
+cn: /
+automountInformation: -fstype=nfs,tcp,rsize=32768,wsize=32768,rw,intr,hard,nodev,nosuid,noatime nas-server.intern:/&amp;
+&lt;/pre&gt;&lt;/blockquote&gt;&lt;/p&gt;
+
+&lt;p&gt;The last step to remember is to mount the relevant mount points in
+tjener.intern by adding them to /etc/fstab, creating the mount
+directories using mkdir and running &quot;mount -a&quot; to mount them.&lt;/p&gt;
+
+&lt;p&gt;When this is done, your users should be able to access the files on
+the storage server directly by just visiting the
+/tjener/nas-server/storage/ directory using any application on any
+workstation, LTSP client or LTSP server.&lt;/p&gt;
