The Debian installer could be
+a lot quicker. When we install more than 2000 packages in
+Skolelinux / Debian Edu using
+tasksel in the installer, unpacking the binary packages take forever.
+A part of the slow I/O issue was discussed in
+bug #613428 about too
+much file system sync-ing done by dpkg, which is the package
+responsible for unpacking the binary packages. Other parts (like code
+executed by postinst scripts) might also sync to disk during
+installation. All this sync-ing to disk do not really make sense to
+me. If the machine crash half-way through, I start over, I do not try
+to salvage the half installed system. So the failure sync-ing is
+supposed to protect against, hardware or system crash, is not really
+relevant while the installer is running.
+
+
A few days ago, I thought of a way to get rid of all the file
+system sync()-ing in a fairly non-intrusive way, without the need to
+change the code in several packages. The idea is not new, but I have
+not heard anyone propose the approach using dpkg-divert before. It
+depend on the small and clever package
+eatmydata, which
+uses LD_PRELOAD to replace the system functions for syncing data to
+disk with functions doing nothing, thus allowing programs to live
+dangerous while speeding up disk I/O significantly. Instead of
+modifying the implementation of dpkg, apt and tasksel (which are the
+packages responsible for selecting, fetching and installing packages),
+it occurred to me that we could just divert the programs away, replace
+them with a simple shell wrapper calling
+"eatmydata $program $@", to get the same effect.
+Two days ago I decided to test the idea, and wrapped up a simple
+implementation for the Debian Edu udeb.
+
+
The effect was stunning. In my first test it reduced the running
+time of the pkgsel step (installing tasks) from 64 to less than 44
+minutes (20 minutes shaved off the installation) on an old Dell
+Latitude D505 machine. I am not quite sure what the optimised time
+would have been, as I messed up the testing a bit, causing the debconf
+priority to get low enough for two questions to pop up during
+installation. As soon as I saw the questions I moved the installation
+along, but do not know how long the question were holding up the
+installation. I did some more measurements using Debian Edu Jessie,
+and got these results. The time measured is the time stamp in
+/var/log/syslog between the "pkgsel: starting tasksel" and the
+"pkgsel: finishing up" lines, if you want to do the same measurement
+yourself. In Debian Edu, the tasksel dialog do not show up, and the
+timing thus do not depend on how quickly the user handle the tasksel
+dialog.

+
The test is done using a netinst ISO on a USB stick, so some of the
+time is spent downloading packages. The connection to the Internet
+was 100Mbit/s during testing, so downloading should not be a
+significant factor in the measurement. Download typically took a few
+seconds to a few minutes, depending on the amount of packages being
+installed.
+
+
The speedup is implemented by using two hooks in
+Debian
+Installer, the pre-pkgsel.d hook to set up the diverts, and the
+finish-install.d hook to remove the divert at the end of the
+installation. I picked the pre-pkgsel.d hook instead of the
+post-base-installer.d hook because I test using an ISO without the
+eatmydata package included, and the post-base-installer.d hook in
+Debian Edu can only operate on packages included in the ISO. The
+negative effect of this is that I am unable to activate this
+optimization for the kernel installation step in d-i. If the code is
+moved to the post-base-installer.d hook, the speedup would be larger
+for the entire installation.
+
+
I've implemented this in the
+debian-edu-install
+git repository, and plan to provide the optimization as part of the
+Debian Edu installation. If you want to test this yourself, you can
+create two files in the installer (or in an udeb). One shell script
+need do go into /usr/lib/pre-pkgsel.d/, with content like this:
+
+
+#!/bin/sh
+set -e
+. /usr/share/debconf/confmodule
+info() {
+ logger -t my-pkgsel "info: $*"
+}
+error() {
+ logger -t my-pkgsel "error: $*"
+}
+override_install() {
+ apt-install eatmydata || true
+ if [ -x /target/usr/bin/eatmydata ] ; then
+ for bin in dpkg apt-get aptitude tasksel ; do
+ file=/usr/bin/$bin
+ # Test that the file exist and have not been diverted already.
+ if [ -f /target$file ] ; then
+ info "diverting $file using eatmydata"
+ printf "#!/bin/sh\neatmydata $bin.distrib \"\$@\"\n" \
+ > /target$file.edu
+ chmod 755 /target$file.edu
+ in-target dpkg-divert --package debian-edu-config \
+ --rename --quiet --add $file
+ ln -sf ./$bin.edu /target$file
+ else
+ error "unable to divert $file, as it is missing."
+ fi
+ done
+ else
+ error "unable to find /usr/bin/eatmydata after installing the eatmydata pacage"
+ fi
+}
+
+override_install
+
+
+
To clean up, another shell script should go into
+/usr/lib/finish-install.d/ with code like this:
+
+
+#! /bin/sh -e
+. /usr/share/debconf/confmodule
+error() {
+ logger -t my-finish-install "error: $@"
+}
+remove_install_override() {
+ for bin in dpkg apt-get aptitude tasksel ; do
+ file=/usr/bin/$bin
+ if [ -x /target$file.edu ] ; then
+ rm /target$file
+ in-target dpkg-divert --package debian-edu-config \
+ --rename --quiet --remove $file
+ rm /target$file.edu
+ else
+ error "Missing divert for $file."
+ fi
+ done
+ sync # Flush file buffers before continuing
+}
+
+remove_install_override
+
+
+
In Debian Edu, I placed both code fragments in a separate script
+edu-eatmydata-install and call it from the pre-pkgsel.d and
+finish-install.d scripts.
+
+
By now you might ask if this change should get into the normal
+Debian installer too? I suspect it should, but am not sure the
+current debian-installer coordinators find it useful enough. It also
+depend on the side effects of the change. I'm not aware of any, but I
+guess we will see if the change is safe after some more testing.
+Perhaps there is some package in Debian depending on sync() and
+fsync() having effect? Perhaps it should go into its own udeb, to
+allow those of us wanting to enable it to do so without affecting
+everyone.
+
+
Update 2014-09-24: Since a few days ago, enabling this optimization
+will break installation of all programs using gnutls because of
+bug #702711. An updated
+eatmydata package in Debian will solve it.

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 Debian Edu / Skolelinux, 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
-Skolelinux Drift AS, where I am
-on the board of directors, asked about how to do this. The steps to
-get this working are the following:
-
-
-
-- Add new storage server in DNS. I use nas-server.intern as the
-example host here.
-
-- Add automoun LDAP information about this server in LDAP, to allow
-all clients to automatically mount it on reqeust.
-
-- Add the relevant entries in tjener.intern:/etc/fstab, because
-tjener.intern do not use automount to avoid mounting loops.
-
-
-
-
DNS entries are added in GOsa², and not described here. Follow the
-instructions
-in the manual (Machine Management with GOsa² in section Getting
-started).
-
-
Ensure that the NFS export points on the server are exported to the
-relevant subnets or machines:

Yesterday, I had the pleasure of attending a talk with the
+Norwegian Unix User Group about
+the
+OpenPGP keyserver pool sks-keyservers.net, and was very happy to
+learn that there is a large set of publicly available key servers to
+use when looking for peoples public key. So far I have used
+subkeys.pgp.net, and some times wwwkeys.nl.pgp.net when the former
+were misbehaving, but those days are ended. The servers I have used
+up until yesterday have been slow and some times unavailable. I hope
+those problems are gone now.
+
+
Behind the round robin DNS entry of the
+sks-keyservers.net service
+there is a pool of more than 100 keyservers which are checked every
+day to ensure they are well connected and up to date. It must be
+better than what I have used so far. :)
+
+
Yesterdays speaker told me that the service is the default
+keyserver provided by the default configuration in GnuPG, but this do
+not seem to be used in Debian. Perhaps it should?
+
+
Anyway, I've updated my ~/.gnupg/options file to now include this
+line:
-root@tjener:~# showmount -e nas-server
-Export list for nas-server:
-/storage 10.0.0.0/8
-root@tjener:~#
+keyserver pool.sks-keyservers.net
-
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.
-
-
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.
+
With GnuPG version 2 one can also locate the keyserver using SRV
+entries in DNS. Just for fun, I did just that at work, so now every
+user of GnuPG at the University of Oslo should find a OpenGPG
+keyserver automatically should their need it:
-ldapvi --ldap-conf -ZD '(cn=admin)' -b ou=automount,dc=skole,dc=skolelinux,dc=no
+% host -t srv _pgpkey-http._tcp.uio.no
+_pgpkey-http._tcp.uio.no has SRV record 0 100 11371 pool.sks-keyservers.net.
+%
-
When the editor show up, add the following LDAP objects at the
-bottom of the document. The "/&" 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.
-
-
-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

-cn: /
-automountInformation: -fstype=nfs,tcp,rsize=32768,wsize=32768,rw,intr,hard,nodev,nosuid,noatime nas-server.intern:/&
-
-
-
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 "mount -a" to mount them.
-
-
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.
+
Now if only
+the
+HKP lookup protocol supported finding signature paths, I would be

+normally do not want that, but to find a trust path from my key to
+another key. Given a user ID or key ID, I would like to find (and
+download) the keys representing a signature path from my key to the
+key in question, to be able to get a trust path between the two keys.
+This is as far as I can tell not possible today. Perhaps something

Two years later, I am still not sure if it is legal here in Norway

+create "personal" or "non-commercial" videos or get a license

+possibility to recycle computers, weeded out from offices. The
+servers and desktops are running for more than two years and they are
+working reliable.

We have two servers (one tjener and one terminal server), 45
+workstations in three classrooms and seven laptops as a mobile
+solution for all classrooms. These machines are all booting from the
+terminal server. In the moment we are installing 30 laptops as mobile
+workstations. Then the pupils have the possibility to work with these
+machines in their classrooms. Internet access is realized by a WLAN
+router, connected to the schools network. This is all done without a
+dedicated system administrator or a computer science teacher.

Teachers and pupils are Windows users. <Irony on> And Linux

Which strategy do you believe is the right one to use to
+get schools to use free software?
-
+
In Germany we have the situation: every school is free to decide
+which software they want to use. This decision is influenced by
+teachers who learned to use Windows and MS Office. They buy a PC with
+Windows preinstalled and an additional testing version of MS
+Office. They don't know about the possibility to use Free Software
+instead. Another problem are the publisher of school books. They
+develop their software, added to the school books, for Windows.

This summer I finally had time to continue working on the Norwegian
+docbook version of the 2004 book
+Free Culture by Lawrence Lessig,
+to get a Norwegian text explaining the problems with todays copyright
+law. Yesterday, I finally completed translated the book text. There
+are still some foot/end notes left to translate, the colophon page
+need to be rewritten, and a few words and phrases still need to be
+translated, but the Norwegian text is ready for the first proof
+reading. :) More spell checking is needed, and several illustrations
+need to be cleaned up. The work stopped up because I had to give
+priority to other projects the last year, and the progress graph of
+the translation show this very well:
+
+
+
+
If you want to read the result, check out the
+github
+project pages and the
+PDF,
+EPUB
+and HTML version available in the
+archive
+directory.
+
+
Please report typos, bugs and improvements to the github project if
+you find any.
