94 <p>About Debian Edu and Skolelinux</p>
95
96 <p>Debian Edu, also known as Skolelinux, is a Linux distribution based
97 on Debian providing an out-of-the box environment of a completely
98 configured school network. Immediately after installation a school
99 server running all services needed for a school network is set up just
100 waiting for users and machines being added via GOsa², a comfortable
101 Web-UI. A netbooting environment is prepared using PXE, so after
102 initial installation of the main server from CD or USB stick all other
103 machines can be installed via the network. The provided school server
104 provides LDAP database and Kerberos authentication service,
105 centralized home directories, DHCP server, web proxy and many other
106 services. The desktop contains more than 60 educational software
107 packages and more are available from the Debian archive, and schools
108 can choose between KDE, Gnome, LXDE and Xfce desktop environment.</p>
109
110 <p>This is the seventh test release based on Debian Wheezy. Basically
111 this is an updated and slightly improved version compared to the
112 Squeeze release.</p>
113
114 <p>Notes for upgrades from Alpha Prereleases</p>
115
116 <p>Alpha based installations should reinstall or downgrade the
117 versions of gosa and libpam-mklocaluser to the ones used in this beta
118 release. Both alpha and beta0 based installations should reinstall or
119 deal with gosa.conf manually; there are two options: (1) Keep
120 gosa.conf and edit this file as outlined on the mailing list. (2)
121 Accept the new version of gosa.conf and replace both contained admin
122 password placeholders with the password hashes found in the old one
123 (backup copy!). In both cases all users need to change their password
124 to make sure a password is set for CIFS access to their home
125 directory.</p>
126

128 <p>cheers,
129 <br> Holger</p>

144 <div class="date">10th September 2013</div>
145 <div class="body"><p>I was introduced to the
146 <a href="http://www.freedomboxfoundation.org/">Freedombox project</a>
147 in 2010, when Eben Moglen presented his vision about serving the need
148 of non-technical people to keep their personal information private and
149 within the legal protection of their own homes. The idea is to give
150 people back the power over their network and machines, and return
151 Internet back to its intended peer-to-peer architecture. Instead of
152 depending on a central service, the Freedombox will give everyone
153 control over their own basic infrastructure.</p>
154
155 <p>I've intended to join the effort since then, but other tasks have
156 taken priority. But this summers nasty news about the misuse of trust
157 and privilege exercised by the "western" intelligence gathering
158 communities increased my eagerness to contribute to a point where I
159 actually started working on the project a while back.</p>
160
161 <p>The <a href="https://alioth.debian.org/projects/freedombox/">initial
162 Debian initiative</a> based on the vision from Eben Moglen, is to
163 create a simple and cheap Debian based appliance that anyone can hook
164 up in their home and get access to secure and private services and
165 communication. The initial deployment platform have been the
166 <a href="http://www.globalscaletechnologies.com/t-dreamplugdetails.aspx">Dreamplug</a>,
167 which is a piece of hardware I do not own. So to be able to test what
168 the current Freedombox setup look like, I had to come up with a way to install
169 it on some hardware I do have access to. I have rewritten the
170 <a href="https://github.com/NickDaly/freedom-maker">freedom-maker</a>
171 image build framework to use .deb packages instead of only copying
172 setup into the boot images, and thanks to this rewrite I am able to
173 set up any machine supported by Debian Wheezy as a Freedombox, using
174 the previously mentioned deb (and a few support debs for packages
175 missing in Debian).</p>
176
177 <p>The current Freedombox setup consist of a set of bootstrapping
178 scripts
179 (<a href="https://github.com/petterreinholdtsen/freedombox-setup">freedombox-setup</a>),
180 and a administrative web interface
181 (<a href="https://github.com/NickDaly/Plinth">plinth</a> + exmachina +
182 withsqlite), as well as a privacy enhancing proxy based on
183 <a href="http://packages.qa.debian.org/privoxy">privoxy</a>
184 (freedombox-privoxy). There is also a web/javascript based XMPP
185 client (<a href="http://packages.qa.debian.org/jwchat">jwchat</a>)
186 trying (unsuccessfully so far) to talk to the XMPP server
187 (<a href="http://packages.qa.debian.org/ejabberd">ejabberd</a>). The
188 web interface is pluggable, and the goal is to use it to enable OpenID
189 services, mesh network connectivity, use of TOR, etc, etc. Not much of
190 this is really working yet, see
191 <a href="https://github.com/NickDaly/freedombox-todos/blob/master/TODO">the
192 project TODO</a> for links to GIT repositories. Most of the code is
193 on github at the moment. The HTTP proxy is operational out of the
194 box, and the admin web interface can be used to add/remove plinth
195 users. I've not been able to do anything else with it so far, but
196 know there are several branches spread around github and other places
197 with lots of half baked features.</p>
198
199 <p>Anyway, if you want to have a look at the current state, the
200 following recipes should work to give you a test machine to poke
201 at.</p>
202
203 <p><strong>Debian Wheezy amd64</strong></p>
204
205 <ol>
206
207 <li>Fetch normal Debian Wheezy installation ISO.</li>
208 <li>Boot from it, either as CD or USB stick.</li>
209 <li><p>Press [tab] on the boot prompt and add this as a boot argument
210 to the Debian installer:<p>
211 <pre>url=<a href="http://www.reinholdtsen.name/freedombox/preseed-wheezy.dat">http://www.reinholdtsen.name/freedombox/preseed-wheezy.dat</a></pre></li>
212
213 <li>Answer the few language/region/password questions and pick disk to
214 install on.</li>
215
216 <li>When the installation is finished and the machine have rebooted a
217 few times, your Freedombox is ready for testing.</li>
218
219 </ol>
220
221 <p><strong>Raspberry Pi Raspbian</strong></p>
222
223 <ol>
224
225 <li>Fetch a Raspbian SD card image, create SD card.</li>
226 <li>Boot from SD card, extend file system to fill the card completely.</li>
227 <li><p>Log in and add this to /etc/sources.list:</p>
228 <pre>
229 deb <a href="http://www.reinholdtsen.name/freedombox/">http://www.reinholdtsen.name/freedombox</a> wheezy main
230 </pre></li>
231 <li><p>Run this as root:</p>
232 <pre>
233 wget -O - http://www.reinholdtsen.name/freedombox/BE1A583D.asc | \
234 apt-key add -
235 apt-get update
236 apt-get install freedombox-setup
237 /usr/lib/freedombox/setup
238 </pre></li>
239 <li>Reboot into your freshly created Freedombox.</li>
240
241 </ol>
242
243 <p>You can test it on other architectures too, but because the
244 freedombox-privoxy package is binary, it will only work as intended on
245 the architectures where I have had time to build the binary and put it
246 in my APT repository. But do not let this stop you. It is only a
247 short "<tt>apt-get source -b freedombox-privoxy</tt>" away. :)</p>
248
249 <p>Note that by default Freedombox is a DHCP server on the
250 192.168.1.0/24 subnet, so if this is your subnet be careful and turn
251 off the DHCP server by running "<tt>update-rc.d isc-dhcp-server
252 disable</tt>" as root.</p>
253
254 <p>Please let me know if this works for you, or if you have any
255 problems. We gather on the IRC channel
256 <a href="irc://irc.debian.org:6667/%23freedombox">#freedombox</a> on
257 irc.debian.org and the
258 <a href="http://lists.alioth.debian.org/cgi-bin/mailman/listinfo/freedombox-discuss">project
259 mailing list</a>.</p>
260
261 <p>Once you get your freedombox operational, you can visit
262 <tt>http://your-host-name:8001/</tt> to see the state of the plint
263 welcome screen (dead end - do not be surprised if you are unable to
264 get past it), and next visit <tt>http://your-host-name:8001/help/</tt>
265 to look at the rest of plinth. The default user is 'admin' and the
266 default password is 'secret'.</p>

280 <div class="date"> 8th September 2013</div>
281 <div class="body"><p>I 2011 raderte et stortingsflertall bestående av Høyre og
282 Arbeiderpartiet vekk en betydelig del av privatsfæren til det norske
283 folk. Det ble vedtatt at det skulle registreres og lagres i et halvt
284 år hvor alle som bærer på en mobiltelefon befinner seg, hvem de
285 snakker med og hvor lenge de snakket sammen. Det skal også
286 registreres hvem de sendte SMS-meldinger til, hvem en har sendt epost
287 til, og hvilke nett-tjenere en besøkte. Saken er kjent som
288 <a href="http://beta.holderdeord.no/issues/innfore-datalagringsdirektivet">Datalagringsdirektivet
289 (DLD)</a>, og innebærer at alle innbyggerne og andre innenfor Norges
290 grenser overvåkes døgnet rundt. Det ble i praksis innført brev og
291 besøkskontroll av hele befolkningen. Rapporter fra de landene som
292 allerede har innført slik total lagring av borgernes
293 kommunikasjonsmønstre forteller at det ikke hjelper i
294 kriminalitetsbekjempelsen. Den norske prislappen blir mange hundre
295 millioner, uten at det ser ut til å bidra positivt til politiets
296 arbeide. Jeg synes flere hundre millioner i stedet burde vært brukt
297 på noe som kan dokumenteres å ha effekt i kriminalitetsbekjempelsen.
298 Se mer på
299 <a href="http://no.wikipedia.org/wiki/Datalagringsdirektivet">Wikipedia</a>
300 og <a href="http://www.uhuru.biz/?cat=84">Jon Wessel-Aas</a>.</p>
301
302 <p>Hva er problemet, tenkter du kanskje? Et åpenbart problem er at
303 medienes kildevern i praksis blir radert ut. Den innsamlede
304 informasjonen gjør det mulig å finne ut hvem som har snakket med
305 journalister på telefon, SMS og epost, og hvem som har vært i nærheten
306 av journalister så sant begge bar med seg en telefon. Et annet er at
307 advokatvernet blir sterkt redusert, der politiet kan finne ut hvem
308 som har snakket med en advokat når, eller vært i møter en med advokat.
309 Et tredje er at svært personlig informasjon kan avledes fra hvilke
310 nettsteder en har besøkt. Har en besøkt hivnorge.no,
311 swingersnorge.com eller andre sider som kan brukes til avlede
312 interesser som hører til privatsfæren, vil denne informasjonen være
313 tilgjengelig takket være datalagringsdirektivet.</p>
314
315 <p>De fleste partiene var mot, kun to partier stemte for. Høyre og
316 Arbeiderpartiet. Og både Høyre og Arbeiderpartiet i Oslo har
317 DLD-forkjempere på toppen av sine lister (har ikke sjekket de andre
318 fylkene). Det er dermed helt uaktuelt for meg å stemme på disse
319 partiene. Her er oversikten over partienes valglister i Oslo, med
320 informasjon om hvem som stemte hva i første DLD-votering i Stortinget,
321 basert på informasjon fra mine venner i

564 <div class="date">22nd August 2013</div>
565 <div class="body"><p>The second wheezy based beta release of Debian Edu was wrapped up
566 today, slightly delayed because of some bugs in the initial Windows
567 integration fixes . This is the release announcement:</p>
568
569 <p><strong>New features for Debian Edu 7.1+edu0~b1 released 2013-08-22</strong></p>
570
571 <p>These are the release notes for Debian Edu / Skolelinux
572 7.1+edu0~b1, based on Debian with codename "Wheezy".</p>
573
574 <p><strong>About Debian Edu and Skolelinux</strong></p>
575
576 <p><a href="http://www.skolelinux.org/">Debian Edu, also known as
577 Skolelinux</a>, is a Linux distribution based on Debian providing an
578 out-of-the box environment of a completely configured school
579 network. Immediately after installation a school server running all
580 services needed for a school network is set up just waiting for users
581 and machines being added via GOsa², a comfortable Web-UI. A netbooting
582 environment is prepared using PXE, so after initial installation of
583 the main server from CD or USB stick all other machines can be
584 installed via the network. The provided school server provides LDAP
585 database and Kerberos authentication service, centralized home
586 directories, DHCP server, web proxy and many other services. The
587 desktop contains
588 <a href="http://people.skolelinux.org/pere/blog/Educational_applications_included_in_Debian_Edu___Skolelinux__the_screenshot_collection____.html">more
589 than 60 educational software packages</a> and more are available from
590 the Debian archive, and schools can choose between KDE, Gnome, LXDE
591 and Xfce desktop environment.</p>
592
593 <p>This is the sixth test release based on Debian Wheezy. Basically this
594 is an updated and slightly improved version compared to the Squeeze
595 release.</p>
596
597 <p>ALERT: Alpha based installations should reinstall or downgrade the
598 versions of gosa and libpam-mklocaluser to the ones used in this beta
599 release. Both alpha and beta0 based installations should reinstall or
600 deal with gosa.conf manually; there are two options: (1) Keep
601 gosa.conf and edit this file as outlined
602 <a href="http://lists.debian.org/debian-edu/2013/08/msg00127.html">on
603 the mailing list</a>. (2) Accept the new version of gosa.conf and
604 replace both contained admin password placeholders with the password
605 hashes found in the old one (backup copy!). In both cases every user
606 need to change their their password to make sure a password is set for
607 CIFS access to their home directory.</p>
608
609 <p><strong>Software updates</strong></p>
610
611 <ul>
612
613 <li>Added ssh askpass packages to default installation, to ensure ssh
614 work also without a attached tty.</li>
615 <li>Add the command-not-found package to the default installation to
616 make it easier to figure out where to find missing command line
617 tools. Please note, that the command 'update-command-not-found'
618 has to be run as root to actually make it useful (internet access
619 required).</li>
620
621 </ul>
622
623 <p><strong>Other changes</strong></p>
624
625 <ul>
626
627 <li>Adjusted the USB stick ISO image build to include every tool
628 needed for desktop=xfce installations.</li>
629 <li>Adjust thin-client-server task to work when installing from USB
630 stick ISO image.</li>
631 <li>Made new grub artwork (changed png from indexed to RGB format).</li>
632 <li>Minor cleanup in the CUPS setup.</li>
633 <li>Make sure that bootstrapping of the Samba domain really happens
634 during installation of the main server and adjust SID handling to
635 cope with this.</li>
636 <li>Make Samba passwords changeable (again) via GOsa².</li>
637 <li>Fix generation of LM and NT password hashes via GOsa² to avoid
638 empty password hashes.</li>
639 <li>Adapted Samba machine domain joining to latest change in the
640 smbldap-tools Perl package, fixing bugs blocking Windows machines
641 from joining the Samba domain.</li>

703 <div class="date">18th August 2013</div>
704 <div class="body"><p>Earlier, I reported about
705 <a href="http://people.skolelinux.org/pere/blog/How_to_fix_a_Thinkpad_X230_with_a_broken_180_GB_SSD_disk.html">my
706 problems using an Intel SSD 520 Series 180 GB disk</a>. Friday I was
707 told by IBM that the original disk should be thrown away. And as
708 there no longer was a problem if I bricked the firmware, I decided
709 today to try to install Intel firmware to replace the Lenovo firmware
710 currently on the disk.</p>
711
712 <p>I searched the Intel site for firmware, and found
713 <a href="https://downloadcenter.intel.com/Detail_Desc.aspx?agr=Y&ProdId=3472&DwnldID=18363&ProductFamily=Solid-State+Drives+and+Caching&ProductLine=Intel%c2%ae+High+Performance+Solid-State+Drive&ProductProduct=Intel%c2%ae+SSD+520+Series+(180GB%2c+2.5in+SATA+6Gb%2fs%2c+25nm%2c+MLC)&lang=eng">issdfut_2.0.4.iso</a>
714 (aka Intel SATA Solid-State Drive Firmware Update Tool) which
715 according to the site should contain the latest firmware for SSD
716 disks. I inserted the broken disk in one of my spare laptops and
717 booted the ISO from a USB stick. The disk was recognized, but the
718 program claimed the newest firmware already were installed and refused
719 to insert any Intel firmware. So no change, and the disk is still
720 unable to handle write load. :( I guess the only way to get them
721 working would be if Lenovo releases new firmware. No idea how likely
722 that is. Anyway, just blogging about this test for completeness. I
723 got a working Samsung disk, and see no point in spending more time on
724 the broken disks.</p>

738 <div class="date"> 2nd August 2013</div>
739 <div class="body"><p>It has been a while since my last update. Since last summer, I
740 have worked on a Norwegian
741 <a href="http://www.docbook.org/">docbook</a> version of the 2004 book
742 <a href="http://free-culture.cc/">Free Culture</a> by Lawrence Lessig,
743 to get a Norwegian text explaining the problems with the copyright
744 law. Yesterday, I finally broken the 90% mark, when counting the
745 number of strings to translate. Due to real life constraints, I have
746 not had time to work on it since March, but when the summer broke out,
747 I found time to work on it again. Still lots of work left, but the
748 first draft is nearing completion. I created a graph to show the
749 progress of the translation:</p>
750
751 <p><img width="80%" align="center" src="https://github.com/petterreinholdtsen/free-culture-lessig/raw/master/progress.png"></p>
752
753 <p>When the first draft is done, the translated text need to be
754 proof read, and the remaining formatting problems with images and SVG
755 drawings need to be fixed. There are probably also some index entries
756 missing that need to be added. This can be done by comparing the
757 index entries listed in the SiSU version of the book, or comparing the
758 English docbook version with the paper version. Last, the colophon
759 page with ISBN numbers etc need to be wrapped up before the release is
760 done. I should also figure out how to get correct Norwegian sorting
761 of the index pages. All docbook tools I have tried so far (xmlto,
762 docbook-xsl, dblatex) get the order of symbols and the special
763 Norwegian letters ÆØÅ wrong.</p>
764
765 <p>There is still need for translators and people with docbook
766 knowledge, to be able to get a good looking book (I still struggle
767 with dblatex, xmlto and docbook-xsl) as well as to do the draft
768 translation and proof reading. And I would like the figures to be
769 redrawn as SVGs to make it easy to translate them. Any SVG master
770 around? There are also some legal terms that are unfamiliar to me.
771 If you want to help, please get in touch with me, and check out the
772 project files currently available from
773 <a href="https://github.com/petterreinholdtsen/free-culture-lessig">github</a>.</p>
774
775 <p>If you are curious what the translated book currently look like,
776 the updated
777 <a href="https://github.com/petterreinholdtsen/free-culture-lessig/blob/master/archive/freeculture.nb.pdf?raw=true">PDF</a>
778 and
779 <a href="https://github.com/petterreinholdtsen/free-culture-lessig/blob/master/archive/freeculture.nb.epub?raw=true">EPUB</a>
780 are published on github. The HTML version is published as well, but
781 github hand it out with MIME type text/plain, confusing browsers, so I
782 saw no point in linking to that version.</p>

807
808 <p><a href="http://www.skolelinux.org/">Debian Edu, also known as
809 Skolelinux</a>, is a Linux distribution based on Debian providing an

821 than 60 educational software packages</a> and more are available from
822 the Debian archive, and schools can choose between KDE, Gnome, LXDE
823 and Xfce desktop environment.</p>
824
825 <p>This is the fifth test release based on Debian Wheezy. Basically
826 this is an updated and slightly improved version compared to the
827 Squeeze release.</p>
828
829 <p>ALERT: Alpha based installations should reinstall or downgrade the
830 versions of gosa and libpam-mklocaluser to the ones used in this beta
831 release.</p>
832
833 <p><strong>Software updates</strong></p>
834
835 <ul>
836
837 <li>Switched roaming workstation profiles from wicd to network-manager
838 for network configuration, as wicd didn't work any more.</li>
839 <li>Changed version numbers of patched gosa and libpam-mklocaluser
840 packages to make sure our locally patched versions will be replaced
841 by the official packages when they are released from Debian. Those
842 installing alpha version need to reinstall or manually downgrade gosa
843 and libpam-mklocaluser.</li>
844 <li>Added bluetooth tools to the default desktop (bluedevil, blueman).</li>
845 <li>Added tools for sharing the desktop on KDE (krdc, krfb).</li>
846 <li>Added valgrind to the default installation for easier debugging of
847 crash bugs.</li>
848
849 </ul>
850
851 <p><strong>Other changes</strong></p>
852
853 <ul>
854
855 <li>Fixed artwork package to work with gnome, no longer break
856 desktop=gnome installations.</li>
857 <li>Adjusted installer to now work when forced to use a proxy with the
858 netinst CD.</li>
859 <li>Fixed code detecting and setting/loading hardware specific
860 setup/firmware to work more robust out of the box.</li>
861 <li>Adjusted Kerberos setup to detect realm and server settings at
862 install time instead of dynamically at run time. This avoid a crash
863 with krb5-auth-dialog on diskless workstations without a DNS name.</li>
864 <li>Worked around misfeature in network-manager not calling the dhclient
865 exit hooks, causing automatic proxy configuration and automatic host
866 name setting at run time to work again.</li>

934 <div class="date">17th July 2013</div>
935 <div class="body"><p>Today I switched to
936 <a href="http://people.skolelinux.org/pere/blog/The_Thinkpad_is_dead__long_live_the_Thinkpad_X230_.html">my
937 new laptop</a>. I've previously written about the problems I had with
938 my new Thinkpad X230, which was delivered with an
939 <a href="http://people.skolelinux.org/pere/blog/Intel_SSD_520_Series_180_GB_with_Lenovo_firmware_still_lock_up_from_sustained_writes.html">180
940 GB Intel SSD disk with Lenovo firmware</a> that did not handle
941 sustained writes. My hardware supplier have been very forthcoming in
942 trying to find a solution, and after first trying with another
943 identical 180 GB disks they decided to send me a 256 GB Samsung SSD
944 disk instead to fix it once and for all. The Samsung disk survived
945 the installation of Debian with encrypted disks (filling the disk with
946 random data during installation killed the first two), and I thus
947 decided to trust it with my data. I have installed it as a Debian Edu
948 Wheezy roaming workstation hooked up with my Debian Edu Squeeze main
949 server at home using Kerberos and LDAP, and will use it as my work
950 station from now on.</p>
951
952 <p>As this is a solid state disk with no moving parts, I believe the
953 Debian Wheezy default installation need to be tuned a bit to increase
954 performance and increase life time of the disk. The Linux kernel and
955 user space applications do not yet adjust automatically to such
956 environment. To make it easier for my self, I created a draft Debian
957 package <tt>ssd-setup</tt> to handle this tuning. The
958 <a href="http://anonscm.debian.org/gitweb/?p=collab-maint/ssd-setup.git">source
959 for the ssd-setup package</a> is available from collab-maint, and it
960 is set up to adjust the setup of the machine by just installing the
961 package. If there is any non-SSD disk in the machine, the package
962 will refuse to install, as I did not try to write any logic to sort
963 file systems in SSD and non-SSD file systems.</p>
964
965 <p>I consider the package a draft, as I am a bit unsure how to best
966 set up Debian Wheezy with an SSD. It is adjusted to my use case,
967 where I set up the machine with one large encrypted partition (in
968 addition to /boot), put LVM on top of this and set up partitions on
969 top of this again. See the README file in the package source for the
970 references I used to pick the settings. At the moment these
971 parameters are tuned:</p>
972
973 <ul>
974
975 <li>Set up cryptsetup to pass TRIM commands to the physical disk
976 (adding discard to /etc/crypttab)</li>
977
978 <li>Set up LVM to pass on TRIM commands to the underlying device (in
979 this case a cryptsetup partition) by changing issue_discards from
980 0 to 1 in /etc/lvm/lvm.conf.</li>
981
982 <li>Set relatime as a file system option for ext3 and ext4 file
983 systems.</li>
984
985 <li>Tell swap to use TRIM commands by adding 'discard' to
986 /etc/fstab.</li>
987
988 <li>Change I/O scheduler from cfq to deadline using a udev rule.</li>
989
990 <li>Run fstrim on every ext3 and ext4 file system every night (from
991 cron.daily).</li>
992
993 <li>Adjust sysctl values vm.swappiness to 1 and vm.vfs_cache_pressure
994 to 50 to reduce the kernel eagerness to swap out processes.</li>
995
996 </ul>
997
998 <p>During installation, I cancelled the part where the installer fill
999 the disk with random data, as this would kill the SSD performance for
1000 little gain. My goal with the encrypted file system is to ensure
1001 those stealing my laptop end up with a brick and not a working
1002 computer. I have no hope in keeping the really resourceful people
1003 from getting the data on the disk (see
1004 <a href="http://xkcd.com/538/">XKCD #538</a> for an explanation why).
1005 Thus I concluded that adding the discard option to crypttab is the
1006 right thing to do.</p>
1007
1008 <p>I considered using the noop I/O scheduler, as several recommended
1009 it for SSD, but others recommended deadline and a benchmark I found
1010 indicated that deadline might be better for interactive use.</p>
1011
1012 <p>I also considered using the 'discard' file system option for ext3
1013 and ext4, but read that it would give a performance hit ever time a
1014 file is removed, and thought it best to that that slowdown once a day
1015 instead of during my work.</p>
1016
1017 <p>My package do not set up tmpfs on /var/run, /var/lock and /tmp, as
1018 this is already done by Debian Edu.</p>
1019
1020 <p>I have not yet started on the user space tuning. I expect
1021 iceweasel need some tuning, and perhaps other applications too, but
1022 have not yet had time to investigate those parts.</p>
1023
1024 <p>The package should work on Ubuntu too, but I have not yet tested it
1025 there.</p>
1026
1027 <p>As for the answer to the question in the title of this blog post,
1028 as far as I know, the only solution I know about is to replace the
1029 disk. It might be possible to flash it with Intel firmware instead of
1030 the Lenovo firmware. But I have not tried and did not want to do so
1031 without approval from Lenovo as I wanted to keep the warranty on the
1032 disk until a solution was found and they wanted the broken disks
1033 back.</p>

1047 <div class="date">10th July 2013</div>
1048 <div class="body"><p>A few days ago, I wrote about
1049 <a href="http://people.skolelinux.org/pere/blog/The_Thinkpad_is_dead__long_live_the_Thinkpad_X230_.html">the
1050 problems I experienced with my new X230 and its SSD disk</a>, which
1051 was dying during installation because it is unable to cope with
1052 sustained write. My supplier is in contact with
1053 <a href="http://www.lenovo.com/">Lenovo</a>, and they wanted to send a
1054 replacement disk to try to fix the problem. They decided to send an
1055 identical model, so my hopes for a permanent fix was slim.</p>
1056
1057 <p>Anyway, today I got the replacement disk and tried to install
1058 Debian Edu Wheezy with encrypted disk on it. The new disk have the
1059 same firmware version as the original. This time my hope raised
1060 slightly as the installation progressed, as the original disk used to
1061 die after 4-7% of the disk was written to, while this time it kept
1062 going past 10%, 20%, 40% and even past 50%. But around 60%, the disk
1063 died again and I was back on square one. I still do not have a new
1064 laptop with a disk I can trust. I can not live with a disk that might
1065 lock up when I download a new
1066 <a href="http://www.skolelinux.org/">Debian Edu / Skolelinux</a> ISO or
1067 other large files. I look forward to hearing from my supplier with
1068 the next proposal from Lenovo.</p>
1069
1070 <p>The original disk is marked Intel SSD 520 Series 180 GB,
