-&lt;p&gt;It is strange to watch how a bug in Debian causing KDM to fail to
-start at boot when an NVidia video card is used is handled.  The
-problem seem to be that the nvidia X.org driver uses a long time to
-initialize, and this duration is longer than kdm is configured to
-wait.&lt;/p&gt;
-
-&lt;p&gt;I came across two bugs related to this issue,
-&lt;a href=&quot;http://bugs.debian.org/583312&quot;&gt;#583312&lt;/a&gt; initially filed
-against initscripts and passed on to nvidia-glx when it became obvious
-that the nvidia drivers were involved, and
-&lt;a href=&quot;http://bugs.debian.org/524751&quot;&gt;#524751&lt;/a&gt; initially filed against
-kdm and passed on to src:nvidia-graphics-drivers for unknown reasons.&lt;/p&gt;
-
-&lt;p&gt;To me, it seem that no-one is interested in actually solving the
-problem nvidia video card owners experience and make sure the Debian
-distribution work out of the box for these users.  The nvidia driver
-maintainers expect kdm to be set up to wait longer, while kdm expect
-the nvidia driver maintainers to fix the driver to start faster, and
-while they wait for each other I guess the users end up switching to a
-distribution that work for them.  I have no idea what the solution is,
-but I am pretty sure that waiting for each other is not it.&lt;/p&gt;
-
-&lt;p&gt;I wonder why we end up handling bugs this way.&lt;/p&gt;

+               <description>&lt;p&gt;The last few days I have been looking into the status of the LDAP
+directory in Debian Edu, and in the process I started to miss a GUI
+tool to browse the LDAP tree.  The only one I was able to find in
+Debian/Squeeze and Lenny is
+&lt;a href=&quot;http://luma.sourceforge.net/&quot;&gt;LUMA&lt;/a&gt;, which has proved to
+be a great tool to get a overview of the current LDAP directory
+populated by default in Skolelinux.  Thanks to it, I have been able to
+find empty and obsolete subtrees, misplaced objects and duplicate
+objects.  It will be installed by default in Debian/Squeeze.  If you
+are working with LDAP, give it a go. :)&lt;/p&gt;
+
+&lt;p&gt;I did notice one problem with it I have not had time to report to
+the BTS yet.  There is no .desktop file in the package, so the tool do
+not show up in the Gnome and KDE menus, but only deep down in in the
+Debian submenu in KDE.  I hope that can be fixed before Squeeze is
+released.&lt;/p&gt;
+
+&lt;p&gt;I have not yet been able to get it to modify the tree yet.  I would
+like to move objects and remove subtrees directly in the GUI, but have
+not found a way to do that with LUMA yet.  So in the mean time, I use
+&lt;a href=&quot;http://www.lichteblau.com/ldapvi/&quot;&gt;ldapvi&lt;/a&gt; for that.&lt;/p&gt;
+
+&lt;p&gt;If you have tips on other GUI tools for LDAP that might be useful
+in Debian Edu, please contact us on debian-edu@lists.debian.org.&lt;/p&gt;
+
+&lt;p&gt;Update 2010-06-29: Ross Reedstrom tipped us about the
+&lt;a href=&quot;http://packages.qa.debian.org/g/gq.html&quot;&gt;gq&lt;/a&gt; package as a
+useful GUI alternative.  It seem like a good tool, but is unmaintained
+in Debian and got a RC bug keeping it out of Squeeze.  Unless that
+changes, it will not be an option for Debian Edu based on Squeeze.&lt;/p&gt;

+               <description>&lt;p&gt;A while back, I
+&lt;a href=&quot;http://people.skolelinux.org/pere/blog/Time_for_new__LDAP_schemas_replacing_RFC_2307_.html&quot;&gt;complained
+about the fact&lt;/a&gt; that it is not possible with the provided schemas
+for storing DNS and DHCP information in LDAP to combine the two sets
+of information into one LDAP object representing a computer.&lt;/p&gt;
+
+&lt;p&gt;In the mean time, I discovered that a simple fix would be to make
+the dhcpHost object class auxiliary, to allow it to be combined with
+the dNSDomain object class, and thus forming one object for one
+computer when storing both DHCP and DNS information in LDAP.&lt;/p&gt;
+
+&lt;p&gt;If I understand this correctly, it is not safe to do this change
+without also changing the assigned number for the object class, and I
+do not know enough about LDAP schema design to do that properly for
+Debian Edu.&lt;/p&gt;
+
+&lt;p&gt;Anyway, for future reference, this is how I believe we could change
+the
+&lt;a href=&quot;http://tools.ietf.org/html/draft-ietf-dhc-ldap-schema-00&quot;&gt;DHCP
+schema&lt;/a&gt; to solve at least part of the problem with the LDAP schemas
+available today from IETF.&lt;/p&gt;

-&lt;p&gt;When using sitesummary at a site to track machines, it is possible
-to get a list of the machine types in use thanks to the DMI
-information extracted from each machine.  The script to do so is
-included in the sitesummary package, and here is example output from

+               <description>&lt;p&gt;A few times I have had the need to simulate the way tasksel
+installs packages during the normal debian-installer run.  Until now,
+I have ended up letting tasksel do the work, with the annoying problem
+of not getting any feedback at all when something fails (like a
+conffile question from dpkg or a download that fails), using code like
+this:

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

-maintainer:~# /usr/lib/sitesummary/hardware-model-summary
-  vendor                    count
-  Dell Computer Corporation     1
-    PowerEdge 1750              1
-  IBM                           1
-    eserver xSeries 345 -[8670M1X]-     1
-  Intel                         2
-  [no-dmi-info]                 3
-maintainer:~#
+export DEBIAN_FRONTEND=noninteractive
+tasksel --new-install

 &lt;/pre&gt;&lt;/blockquote&gt;
 
 &lt;/pre&gt;&lt;/blockquote&gt;
 

-&lt;p&gt;The quality of the report depend on the quality of the DMI tables
-provided in each machine.  Here there are Intel machines without model
-information listed with Intel as vendor and mo model, and virtual Xen
-machines listed as [no-dmi-info].  One can add -l as a command line
-option to list the individual machines.&lt;/p&gt;
-
-&lt;p&gt;A larger list is
-&lt;a href=&quot;http://narvikskolen.no/sitesummary/&quot;&gt;available from the the
-city of Narvik&lt;/a&gt;, which uses Skolelinux on all their shools and also
-provide the basic sitesummary report publicly.  In their report there
-are ~1400 machines. I know they use both Ubuntu and Skolelinux on
-their machines, and as sitesummary is available in both distributions,
-it is trivial to get all of them to report to the same central
-collector.&lt;/p&gt;

-&lt;p&gt;If Debian is to migrate to upstart on Linux, I expect some init.d
-scripts to migrate (some of) their operations to upstart job while
-keeping the init.d for hurd and kfreebsd.  The packages with such
-needs will need a way to get their init.d scripts to behave
-differently when used with sysvinit and with upstart.  Because of
-this, I had a look at the environment variables set when a init.d
-script is running under upstart, and when it is not.&lt;/p&gt;
-
-&lt;p&gt;With upstart, I notice these environment variables are set when a
-script is started from rcS.d/ (ignoring some irrelevant ones like
-COLUMNS):&lt;/p&gt;
-
-&lt;blockquote&gt;&lt;pre&gt;
-DEFAULT_RUNLEVEL=2
-previous=N
-PREVLEVEL=
-RUNLEVEL=
-runlevel=S
-UPSTART_EVENTS=startup
-UPSTART_INSTANCE=
-UPSTART_JOB=rc-sysinit
-&lt;/pre&gt;&lt;/blockquote&gt;
+This would invoke tasksel, let its automatic task selection pick the
+tasks to install, and continue to install the requested tasks without
+any output what so ever.

 
 

-&lt;p&gt;With sysvinit, these environment variables are set for the same
-script.&lt;/p&gt;
+Recently I revisited this problem while working on the automatic
+package upgrade testing, because tasksel would some times hang without
+any useful feedback, and I want to see what is going on when it
+happen.  Then it occured to me, I can parse the output from tasksel
+when asked to run in test mode, and use that aptitude command line
+printed by tasksel then to simulate the tasksel run.  I ended up using
+code like this:

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

-INIT_VERSION=sysvinit-2.88
-previous=N
-PREVLEVEL=N
-RUNLEVEL=S
-runlevel=S
+export DEBIAN_FRONTEND=noninteractive
+cmd=&quot;$(in_target tasksel -t --new-install | sed &#39;s/debconf-apt-progress -- //&#39;)&quot;
+$cmd

 &lt;/pre&gt;&lt;/blockquote&gt;
 
 &lt;/pre&gt;&lt;/blockquote&gt;
 

-&lt;p&gt;The RUNLEVEL and PREVLEVEL environment variables passed on from
-sysvinit are not set by upstart.  Not sure if it is intentional or not
-to not be compatible with sysvinit in this regard.&lt;/p&gt;
+&lt;p&gt;The content of $cmd is typically something like &quot;&lt;tt&gt;aptitude -q
+--without-recommends -o APT::Install-Recommends=no -y install
+~t^desktop$ ~t^gnome-desktop$ ~t^laptop$ ~pstandard ~prequired
+~pimportant&lt;/tt&gt;&quot;, which will install the gnome desktop task, the
+laptop task and all packages with priority standard , required and
+important, just like tasksel would have done it during
+installation.&lt;/p&gt;

 
 

-&lt;p&gt;For scripts needing to behave differently when upstart is used,
-looking for the UPSTART_JOB environment variable seem to be a good
-choice.&lt;/p&gt;
+&lt;p&gt;A better approach is probably to extend tasksel to be able to
+install packages without using debconf-apt-progress, for use cases
+like this.&lt;/p&gt;

-&lt;p&gt;Det er merkelig hvordan myter om Skolelinux overlever.  En slik
-myte er at Skolelinux ikke kan sentraldriftes og ha sentralt plasserte
-tjenermaskiner.  I siste Computerworld Norge er
-&lt;a href=&quot;http://www.idg.no/computerworld/article169432.ece&quot;&gt;IT-sjef
-Viggo Billdal i Steinkjer intervjuet&lt;/a&gt;, og forteller uten
-blygsel:&lt;/p&gt;
-
-&lt;blockquote&gt;&lt;p&gt;Vi hadde Skolelinux, men det har vi sluttet med. Vi testet
-om det lønte seg med Microsoft eller en åpen plattform. Vi fant ut at
-Microsoft egentlig var totalt sett bedre egnet. Det var store
-driftskostnader med Skolelinux, blant annet på grunn av
-desentraliserte servere. Det var komplisert, så vi gikk vekk fra det
-og bruker nå bare Windows.&lt;/p&gt;&lt;/blockquote&gt;
-
-&lt;p&gt;En &lt;a
-href=&quot;https://init.linpro.no/pipermail/skolelinux.no/bruker/2010-June/009101.html&quot;&gt;rask
-sjekk&lt;/a&gt; mot den norske brukerlista i Skolelinuxprosjektet forteller
-at Steinkjers forsøk foregikk fram til 2004/2005, og at Røysing skole
-i Steinkjer skal ha vært svært fornøyd med Skolelinux men at kommunen
-overkjørte skolen og krevde at de gikk over til Windows.  Et søk på
-nettet sendte meg til
-&lt;a href=&quot;http://www.dn.no/multimedia/archive/00090/Dagens_it_nr__18_90826a.pdf&quot;&gt;Dagens

-
-&lt;blockquote&gt;&lt;p&gt;Inge Tømmerås ved Røysing skole i Steinkjer kjører ennå
-Microsoft, men forteller at kompetanseutfordringen med Skolelinux ikke
-var så stor.  ­ Jeg syntes Skolelinux var utrolig lett å drifte uten
-forkunnskaper. Men man må jo selvsagt ha tilgang på ekstern kompetanse
-til installasjoner og maskinvarefeil, sier Tømmerås.&lt;/p&gt;&lt;/blockquote&gt;

+Norge for tiden, har bestemt seg for med vitende og vilje å bryte
+sentralbanklovens paragraf 14 ved å nekte folk å betale med
+kontanter, og at flere butikker planlegger å følge deres eksempel.
+Jeg synes det er hårreisende hvis de slipper unna med et slikt
+soleklart lovbrudd, og lurer på hva slags muligheter jeg vil ha hvis
+jeg blir nektet å handle med kontanter.  Jeg handler i hovedsak med
+kontanter selv, da jeg anser det som en borgerrett å kunne handle
+anonymt uten at det blir registrert.  For meg er det et angrep på mitt
+personvern å nekte å ta imot kontant betaling.&lt;/p&gt;

 
 

-&lt;p&gt;Som systemarkitekten bak Skolelinux, kan jeg bare riste på hodet
-over påstanden om at Skolelinux krever desentraliserte tjenere.
-Skolelinux-arkitekturen er laget for sentralisert drift og plassering
-av tjenerne lokalt eller sentralt alt etter behov og nettkapasitet.
-Den er modellert på nettverks- og tjenerløsningen som brukes på
-Universitetet i Tromsø og Oslo, der jeg jobber med utvikling av
-driftstjenester.  Dette er det heldigvis noen som har fått med seg, og
-jeg er glad for å kunne sitere fra en kommentar på den overnevnte
-artikkelen.  Min venn og gamle kollega Sturle Sunde forteller der:
+&lt;p&gt;&lt;a href=&quot;http://www.lovdata.no/all/tl-19850524-028-003.html#14&quot;&gt;Paragrafen
+i sentralbankloven&lt;/a&gt; lyder:&lt;/p&gt;

-sjeldan dei tenarane fysisk, men at dei står der gjer skulane mindre
-avhengige av eksterne linjer som er trege eller dyre. Dei minste
-skulane har ikkje eigen tenar. Å bruke sentral tenar er heller ikkje
-noko problem. Småskulane klarar seg fint med 1 mbit-linje til ein
-sentral tenar eller tenaren på ein større skule.&lt;/p&gt;
+&lt;p&gt;§ 14. Tvungent betalingsmiddel&lt;/p&gt;

 
 

-&lt;p&gt;Det beste med Skulelinux er halvtjukke klientar. Dei treng ikkje
-harddisk og brukar minimalt med ressursar på tenaren fordi dei køyrer
-programma lokalt. Eit klasserom med 30 sju-åtte år gamle maskiner har
-mykje meir CPU og RAM totalt enn nokon moderne tenar til under
-millionen. Det trengst to kommandoar på den sentrale tenaren for å
-oppdatere alle klientane, både tynne og halvtjukke. Vi har ingen
-problem med diskar som ryk heller, som var eit problem før fordi
-elevane sat og sparka i maskinene. Og dei krev lite bandbreidde i
-nettet, so det er fullt mogleg å køyre slike på småskular med trege
-linjer mot tenaren på ein større skule.&lt;/p&gt;
+&lt;p&gt;Bankens sedler og mynter er tvungent betalingsmiddel i Norge. Ingen
+er pliktig til i én betaling å ta imot mer enn femogtyve mynter av
+hver enhet.&lt;/p&gt;

 
 

-&lt;p&gt;Flora kommune har nesten 800 Linux-maskiner i sitt skulenett, og
-ein person som tek seg av drift av heile nettet, inkludert tenarar,
-klientar, operativsystem, programvare, heimekontorløysing og
-administrasjon av brukarar.&lt;/p&gt;
+&lt;p&gt;Sterkt skadde sedler og mynter er ikke tvungent
+betalingsmiddel. Banken gir nærmere forskrifter om erstatning for
+bortkomne, brente eller skadde sedler og mynter.&lt;/p&gt;

 
 

-&lt;p&gt;No skal det seiast at vi ikkje køyrer rein Skulelinux ut av
-boksen. Vi har gjort ein del tilpassingar mot noko Novell-greier som
-var der frå før, og som har komplisert installasjonen vår. Etter at
-oppsettet var gjort har løysinga vore stabil og kravd minimalt med
-arbeid.&lt;/p&gt;
+&lt;p&gt;Selv om en avtale inneholder klausul om betaling av en
+pengeforpliktelse i gullverdi, kan skyldneren frigjøre seg med tvungne
+betalingsmidler uten hensyn til denne klausul.&lt;/p&gt;

 &lt;/blockquote&gt;
 
 &lt;/blockquote&gt;
 

-&lt;p&gt;Jeg vet at Narvik, Harstad og Oslo er kommuner der Skolelinux
-sentraldriftes med sentrale tjenere.  Det forteller meg at Steinkjers
-IT-sjef neppe bør skylde på Skolelinux-løsningen for sine 5 år gamle
-minner.&lt;/p&gt;
+&lt;p&gt;Det er med bakgrunn i denne lovet ikke tillatt å nekte å ta imot
+kontakt betaling.  Det er en lov jeg har sans for, og som jeg mener må
+håndheves strengt.&lt;/p&gt;

-&lt;p&gt;The last few days I have done some upgrade testing in Debian, to
-see if the upgrade from Lenny to Squeeze will go smoothly.  A few bugs
-have been discovered and reported in the process
-(&lt;a href=&quot;http://bugs.debian.org/585410&quot;&gt;#585410&lt;/a&gt; in nagios3-cgi,
-&lt;a href=&quot;http://bugs.debian.org/584879&quot;&gt;#584879&lt;/a&gt; already fixed in
-enscript and &lt;a href=&quot;http://bugs.debian.org/584861&quot;&gt;#584861&lt;/a&gt; in
-kdebase-workspace-data), and to get a more regular testing going on, I
-am working on a script to automate the test.&lt;/p&gt;
-
-&lt;p&gt;The idea is to create a Lenny chroot and use tasksel to install a
-Gnome or KDE desktop installation inside the chroot before upgrading
-it.  To ensure no services are started in the chroot, a policy-rc.d
-script is inserted.  To make sure tasksel believe it is to install a
-desktop on a laptop, the tasksel tests are replaced in the chroot
-(only acceptable because this is a throw-away chroot).&lt;/p&gt;
-
-&lt;p&gt;A naive upgrade from Lenny to Squeeze using aptitude dist-upgrade
-currently always fail because udev refuses to upgrade with the kernel
-in Lenny, so to avoid that problem the file /etc/udev/kernel-upgrade
-is created.  The bug report
-&lt;a href=&quot;http://bugs.debian.org/566000&quot;&gt;#566000&lt;/a&gt; make me suspect
-this problem do not trigger in a chroot, but I touch the file anyway
-to make sure the upgrade go well.  Testing on virtual and real
-hardware have failed me because of udev so far, and creating this file
-do the trick in such settings anyway.  This is a
-&lt;a href=&quot;http://www.linuxquestions.org/questions/debian-26/failed-dist-upgrade-due-to-udev-config_sysfs_deprecated-nonsense-804130/&quot;&gt;known
-issue&lt;/a&gt; and the current udev behaviour is intended by the udev
-maintainer because he lack the resources to rewrite udev to keep
-working with old kernels or something like that.  I really wish the
-udev upstream would keep udev backwards compatible, to avoid such
-upgrade problem, but given that they fail to do so, I guess
-documenting the way out of this mess is the best option we got for
-Debian Squeeze.&lt;/p&gt;
-
-&lt;p&gt;Anyway, back to the task at hand, testing upgrades.  This test
-script, which I call &lt;tt&gt;upgrade-test&lt;/tt&gt; for now, is doing the
-trick:&lt;/p&gt;
-
-&lt;blockquote&gt;&lt;pre&gt;
-#!/bin/sh
-set -ex
-
-if [ &quot;$1&quot; ] ; then
-    desktop=$1
-else
-    desktop=gnome
-fi
-
-from=lenny
-to=squeeze
-
-exec &amp;lt; /dev/null
-unset LANG
-mirror=http://ftp.skolelinux.org/debian
-tmpdir=chroot-$from-upgrade-$to-$desktop
-fuser -mv .
-debootstrap $from $tmpdir $mirror
-chroot $tmpdir aptitude update
-cat &gt; $tmpdir/usr/sbin/policy-rc.d &amp;lt;&amp;lt;EOF
-#!/bin/sh
-exit 101
-EOF
-chmod a+rx $tmpdir/usr/sbin/policy-rc.d
-exit_cleanup() {
-    umount $tmpdir/proc
-}
-mount -t proc proc $tmpdir/proc
-# Make sure proc is unmounted also on failure
-trap exit_cleanup EXIT INT
-
-chroot $tmpdir aptitude -y install debconf-utils
-
-# Make sure tasksel autoselection trigger.  It need the test scripts
-# to return the correct answers.
-echo tasksel tasksel/desktop multiselect $desktop | \
-    chroot $tmpdir debconf-set-selections
-
-# Include the desktop and laptop task
-for test in desktop laptop ; do
-    echo &gt; $tmpdir/usr/lib/tasksel/tests/$test &amp;lt;&amp;lt;EOF
-#!/bin/sh
-exit 2
-EOF
-    chmod a+rx $tmpdir/usr/lib/tasksel/tests/$test
-done
-
-DEBIAN_FRONTEND=noninteractive
-DEBIAN_PRIORITY=critical
-export DEBIAN_FRONTEND DEBIAN_PRIORITY
-chroot $tmpdir tasksel --new-install
-
-echo deb $mirror $to main &gt; $tmpdir/etc/apt/sources.list
-chroot $tmpdir aptitude update
-touch $tmpdir/etc/udev/kernel-upgrade
-chroot $tmpdir aptitude -y dist-upgrade
-fuser -mv
-&lt;/pre&gt;&lt;/blockquote&gt;
-
-&lt;p&gt;I suspect it would be useful to test upgrades with both apt-get and
-with aptitude, but I have not had time to look at how they behave
-differently so far.  I hope to get a cron job running to do the test
-regularly and post the result on the web.  The Gnome upgrade currently
-work, while the KDE upgrade fail because of the bug in
-kdebase-workspace-data&lt;/p&gt;

+is a great service.  It is to ODF documents what
+&lt;a href=&quot;http://browsershots.org/&quot;&gt;BrowserShots&lt;/a&gt; is for web
+pages.&lt;/p&gt;

 
 

-&lt;p&gt;I am not quite sure what kind of extract from the huge upgrade logs
-(KDE 167 KiB, Gnome 516 KiB) it make sense to include in this blog
-post, so I will refrain from trying.  I can report that for Gnome,
-aptitude report 760 packages upgraded, 448 newly installed, 129 to
-remove and 1 not upgraded and 1024MB need to be downloaded while for
-KDE the same numbers are 702 packages upgraded, 507 newly installed,
-193 to remove and 0 not upgraded and 1117MB need to be downloaded&lt;/p&gt;
+&lt;p&gt;A while back, I was contacted by Knut Yrvin at the part of Nokia
+that used to be Trolltech, who wanted to help the OfficeShots project
+and wondered if the University of Oslo where I work would be
+interested in supporting the project.  I helped him to navigate his
+request to the right people at work, and his request was answered with
+a spot in the machine room with power and network connected, and Knut
+arranged funding for a machine to fill the spot.  The machine is
+administrated by the OfficeShots people, so I do not have daily
+contact with its progress, and thus from time to time check back to
+see how the project is doing.&lt;/p&gt;

 
 

-&lt;p&gt;I am very happy to notice that the Gnome desktop + laptop upgrade
-is able to migrate to dependency based boot sequencing and parallel
-booting without a hitch.  Was unsure if there were still bugs with
-packages failing to clean up their obsolete init.d script during
-upgrades, and no such problem seem to affect the Gnome desktop+laptop
-packages.&lt;/p&gt;

+&lt;a href=&quot;http://bugs.debian.org/566000&quot;&gt;#566000&lt;/a&gt; make me suspect
+this problem do not trigger in a chroot, but I touch the file anyway
+to make sure the upgrade go well.  Testing on virtual and real
+hardware have failed me because of udev so far, and creating this file
+do the trick in such settings anyway.  This is a
+&lt;a href=&quot;http://www.linuxquestions.org/questions/debian-26/failed-dist-upgrade-due-to-udev-config_sysfs_deprecated-nonsense-804130/&quot;&gt;known
+issue&lt;/a&gt; and the current udev behaviour is intended by the udev
+maintainer because he lack the resources to rewrite udev to keep
+working with old kernels or something like that.  I really wish the
+udev upstream would keep udev backwards compatible, to avoid such
+upgrade problem, but given that they fail to do so, I guess
+documenting the way out of this mess is the best option we got for
+Debian Squeeze.&lt;/p&gt;
+
+&lt;p&gt;Anyway, back to the task at hand, testing upgrades.  This test
+script, which I call &lt;tt&gt;upgrade-test&lt;/tt&gt; for now, is doing the
+trick:&lt;/p&gt;
+
+&lt;blockquote&gt;&lt;pre&gt;
+#!/bin/sh
+set -ex
+
+if [ &quot;$1&quot; ] ; then
+    desktop=$1
+else
+    desktop=gnome
+fi
+
+from=lenny
+to=squeeze
+
+exec &amp;lt; /dev/null
+unset LANG
+mirror=http://ftp.skolelinux.org/debian
+tmpdir=chroot-$from-upgrade-$to-$desktop
+fuser -mv .
+debootstrap $from $tmpdir $mirror
+chroot $tmpdir aptitude update
+cat &gt; $tmpdir/usr/sbin/policy-rc.d &amp;lt;&amp;lt;EOF
+#!/bin/sh
+exit 101
+EOF
+chmod a+rx $tmpdir/usr/sbin/policy-rc.d
+exit_cleanup() {
+    umount $tmpdir/proc
+}
+mount -t proc proc $tmpdir/proc
+# Make sure proc is unmounted also on failure
+trap exit_cleanup EXIT INT
+
+chroot $tmpdir aptitude -y install debconf-utils
+
+# Make sure tasksel autoselection trigger.  It need the test scripts
+# to return the correct answers.
+echo tasksel tasksel/desktop multiselect $desktop | \
+    chroot $tmpdir debconf-set-selections
+
+# Include the desktop and laptop task
+for test in desktop laptop ; do
+    echo &gt; $tmpdir/usr/lib/tasksel/tests/$test &amp;lt;&amp;lt;EOF
+#!/bin/sh
+exit 2
+EOF
+    chmod a+rx $tmpdir/usr/lib/tasksel/tests/$test
+done
+
+DEBIAN_FRONTEND=noninteractive
+DEBIAN_PRIORITY=critical
+export DEBIAN_FRONTEND DEBIAN_PRIORITY
+chroot $tmpdir tasksel --new-install
+
+echo deb $mirror $to main &gt; $tmpdir/etc/apt/sources.list
+chroot $tmpdir aptitude update
+touch $tmpdir/etc/udev/kernel-upgrade
+chroot $tmpdir aptitude -y dist-upgrade
+fuser -mv
+&lt;/pre&gt;&lt;/blockquote&gt;
+
+&lt;p&gt;I suspect it would be useful to test upgrades with both apt-get and
+with aptitude, but I have not had time to look at how they behave
+differently so far.  I hope to get a cron job running to do the test
+regularly and post the result on the web.  The Gnome upgrade currently
+work, while the KDE upgrade fail because of the bug in
+kdebase-workspace-data&lt;/p&gt;
+
+&lt;p&gt;I am not quite sure what kind of extract from the huge upgrade logs
+(KDE 167 KiB, Gnome 516 KiB) it make sense to include in this blog
+post, so I will refrain from trying.  I can report that for Gnome,
+aptitude report 760 packages upgraded, 448 newly installed, 129 to
+remove and 1 not upgraded and 1024MB need to be downloaded while for
+KDE the same numbers are 702 packages upgraded, 507 newly installed,
+193 to remove and 0 not upgraded and 1117MB need to be downloaded&lt;/p&gt;
+
+&lt;p&gt;I am very happy to notice that the Gnome desktop + laptop upgrade
+is able to migrate to dependency based boot sequencing and parallel
+booting without a hitch.  Was unsure if there were still bugs with
+packages failing to clean up their obsolete init.d script during
+upgrades, and no such problem seem to affect the Gnome desktop+laptop
+packages.&lt;/p&gt;

+               <description>&lt;p&gt;Det er merkelig hvordan myter om Skolelinux overlever.  En slik
+myte er at Skolelinux ikke kan sentraldriftes og ha sentralt plasserte
+tjenermaskiner.  I siste Computerworld Norge er
+&lt;a href=&quot;http://www.idg.no/computerworld/article169432.ece&quot;&gt;IT-sjef
+Viggo Billdal i Steinkjer intervjuet&lt;/a&gt;, og forteller uten
+blygsel:&lt;/p&gt;
+
+&lt;blockquote&gt;&lt;p&gt;Vi hadde Skolelinux, men det har vi sluttet med. Vi testet
+om det lønte seg med Microsoft eller en åpen plattform. Vi fant ut at
+Microsoft egentlig var totalt sett bedre egnet. Det var store
+driftskostnader med Skolelinux, blant annet på grunn av
+desentraliserte servere. Det var komplisert, så vi gikk vekk fra det
+og bruker nå bare Windows.&lt;/p&gt;&lt;/blockquote&gt;
+
+&lt;p&gt;En &lt;a
+href=&quot;https://init.linpro.no/pipermail/skolelinux.no/bruker/2010-June/009101.html&quot;&gt;rask
+sjekk&lt;/a&gt; mot den norske brukerlista i Skolelinuxprosjektet forteller
+at Steinkjers forsøk foregikk fram til 2004/2005, og at Røysing skole
+i Steinkjer skal ha vært svært fornøyd med Skolelinux men at kommunen
+overkjørte skolen og krevde at de gikk over til Windows.  Et søk på
+nettet sendte meg til
+&lt;a href=&quot;http://www.dn.no/multimedia/archive/00090/Dagens_it_nr__18_90826a.pdf&quot;&gt;Dagens
+IT nr. 18 2005&lt;/a&gt; hvor en kan lese på side 18:&lt;/p&gt;
+
+&lt;blockquote&gt;&lt;p&gt;Inge Tømmerås ved Røysing skole i Steinkjer kjører ennå
+Microsoft, men forteller at kompetanseutfordringen med Skolelinux ikke
+var så stor.  ­ Jeg syntes Skolelinux var utrolig lett å drifte uten
+forkunnskaper. Men man må jo selvsagt ha tilgang på ekstern kompetanse
+til installasjoner og maskinvarefeil, sier Tømmerås.&lt;/p&gt;&lt;/blockquote&gt;
+
+&lt;p&gt;Som systemarkitekten bak Skolelinux, kan jeg bare riste på hodet
+over påstanden om at Skolelinux krever desentraliserte tjenere.
+Skolelinux-arkitekturen er laget for sentralisert drift og plassering
+av tjenerne lokalt eller sentralt alt etter behov og nettkapasitet.
+Den er modellert på nettverks- og tjenerløsningen som brukes på
+Universitetet i Tromsø og Oslo, der jeg jobber med utvikling av
+driftstjenester.  Dette er det heldigvis noen som har fått med seg, og
+jeg er glad for å kunne sitere fra en kommentar på den overnevnte
+artikkelen.  Min venn og gamle kollega Sturle Sunde forteller der:
+
+&lt;blockquote&gt;
+&lt;p&gt;I Flora kommune køyrer vi Skulelinux på skular med alt frå 15 til
+meir enn 500 elevar. Dei store skulane har eigen tenar, for det er
+mest praktisk. Eg, som er driftsansvarleg for heile nettet, ser
+sjeldan dei tenarane fysisk, men at dei står der gjer skulane mindre
+avhengige av eksterne linjer som er trege eller dyre. Dei minste
+skulane har ikkje eigen tenar. Å bruke sentral tenar er heller ikkje
+noko problem. Småskulane klarar seg fint med 1 mbit-linje til ein
+sentral tenar eller tenaren på ein større skule.&lt;/p&gt;
+
+&lt;p&gt;Det beste med Skulelinux er halvtjukke klientar. Dei treng ikkje
+harddisk og brukar minimalt med ressursar på tenaren fordi dei køyrer
+programma lokalt. Eit klasserom med 30 sju-åtte år gamle maskiner har
+mykje meir CPU og RAM totalt enn nokon moderne tenar til under
+millionen. Det trengst to kommandoar på den sentrale tenaren for å
+oppdatere alle klientane, både tynne og halvtjukke. Vi har ingen
+problem med diskar som ryk heller, som var eit problem før fordi
+elevane sat og sparka i maskinene. Og dei krev lite bandbreidde i
+nettet, so det er fullt mogleg å køyre slike på småskular med trege
+linjer mot tenaren på ein større skule.&lt;/p&gt;
+
+&lt;p&gt;Flora kommune har nesten 800 Linux-maskiner i sitt skulenett, og
+ein person som tek seg av drift av heile nettet, inkludert tenarar,
+klientar, operativsystem, programvare, heimekontorløysing og
+administrasjon av brukarar.&lt;/p&gt;
+
+&lt;p&gt;No skal det seiast at vi ikkje køyrer rein Skulelinux ut av
+boksen. Vi har gjort ein del tilpassingar mot noko Novell-greier som
+var der frå før, og som har komplisert installasjonen vår. Etter at
+oppsettet var gjort har løysinga vore stabil og kravd minimalt med
+arbeid.&lt;/p&gt;
+&lt;/blockquote&gt;
+
+&lt;p&gt;Jeg vet at Narvik, Harstad og Oslo er kommuner der Skolelinux
+sentraldriftes med sentrale tjenere.  Det forteller meg at Steinkjers
+IT-sjef neppe bør skylde på Skolelinux-løsningen for sine 5 år gamle
+minner.&lt;/p&gt;

+               <description>&lt;p&gt;If Debian is to migrate to upstart on Linux, I expect some init.d
+scripts to migrate (some of) their operations to upstart job while
+keeping the init.d for hurd and kfreebsd.  The packages with such
+needs will need a way to get their init.d scripts to behave
+differently when used with sysvinit and with upstart.  Because of
+this, I had a look at the environment variables set when a init.d
+script is running under upstart, and when it is not.&lt;/p&gt;
+
+&lt;p&gt;With upstart, I notice these environment variables are set when a
+script is started from rcS.d/ (ignoring some irrelevant ones like
+COLUMNS):&lt;/p&gt;

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

-export DEBIAN_FRONTEND=noninteractive
-tasksel --new-install
+DEFAULT_RUNLEVEL=2
+previous=N
+PREVLEVEL=
+RUNLEVEL=
+runlevel=S
+UPSTART_EVENTS=startup
+UPSTART_INSTANCE=
+UPSTART_JOB=rc-sysinit

 &lt;/pre&gt;&lt;/blockquote&gt;
 
 &lt;/pre&gt;&lt;/blockquote&gt;
 

-This would invoke tasksel, let its automatic task selection pick the
-tasks to install, and continue to install the requested tasks without
-any output what so ever.
+&lt;p&gt;With sysvinit, these environment variables are set for the same
+script.&lt;/p&gt;

 
 

-Recently I revisited this problem while working on the automatic
-package upgrade testing, because tasksel would some times hang without
-any useful feedback, and I want to see what is going on when it
-happen.  Then it occured to me, I can parse the output from tasksel
-when asked to run in test mode, and use that aptitude command line
-printed by tasksel then to simulate the tasksel run.  I ended up using
-code like this:
+&lt;blockquote&gt;&lt;pre&gt;
+INIT_VERSION=sysvinit-2.88
+previous=N
+PREVLEVEL=N
+RUNLEVEL=S
+runlevel=S
+&lt;/pre&gt;&lt;/blockquote&gt;
+
+&lt;p&gt;The RUNLEVEL and PREVLEVEL environment variables passed on from
+sysvinit are not set by upstart.  Not sure if it is intentional or not
+to not be compatible with sysvinit in this regard.&lt;/p&gt;
+
+&lt;p&gt;For scripts needing to behave differently when upstart is used,
+looking for the UPSTART_JOB environment variable seem to be a good
+choice.&lt;/p&gt;

+               <description>&lt;p&gt;When using sitesummary at a site to track machines, it is possible
+to get a list of the machine types in use thanks to the DMI
+information extracted from each machine.  The script to do so is
+included in the sitesummary package, and here is example output from
+the Skolelinux build servers:&lt;/p&gt;

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

-export DEBIAN_FRONTEND=noninteractive
-cmd=&quot;$(in_target tasksel -t --new-install | sed &#39;s/debconf-apt-progress -- //&#39;)&quot;
-$cmd
+maintainer:~# /usr/lib/sitesummary/hardware-model-summary
+  vendor                    count
+  Dell Computer Corporation     1
+    PowerEdge 1750              1
+  IBM                           1
+    eserver xSeries 345 -[8670M1X]-     1
+  Intel                         2
+  [no-dmi-info]                 3
+maintainer:~#

 &lt;/pre&gt;&lt;/blockquote&gt;
 
 &lt;/pre&gt;&lt;/blockquote&gt;
 

-&lt;p&gt;The content of $cmd is typically something like &quot;&lt;tt&gt;aptitude -q
---without-recommends -o APT::Install-Recommends=no -y install
-~t^desktop$ ~t^gnome-desktop$ ~t^laptop$ ~pstandard ~prequired
-~pimportant&lt;/tt&gt;&quot;, which will install the gnome desktop task, the
-laptop task and all packages with priority standard , required and
-important, just like tasksel would have done it during
-installation.&lt;/p&gt;
+&lt;p&gt;The quality of the report depend on the quality of the DMI tables
+provided in each machine.  Here there are Intel machines without model
+information listed with Intel as vendor and no model, and virtual Xen
+machines listed as [no-dmi-info].  One can add -l as a command line
+option to list the individual machines.&lt;/p&gt;

 
 

-&lt;p&gt;A better approach is probably to extend tasksel to be able to
-install packages without using debconf-apt-progress, for use cases
-like this.&lt;/p&gt;
+&lt;p&gt;A larger list is
+&lt;a href=&quot;http://narvikskolen.no/sitesummary/&quot;&gt;available from the the
+city of Narvik&lt;/a&gt;, which uses Skolelinux on all their shools and also
+provide the basic sitesummary report publicly.  In their report there
+are ~1400 machines. I know they use both Ubuntu and Skolelinux on
+their machines, and as sitesummary is available in both distributions,
+it is trivial to get all of them to report to the same central
+collector.&lt;/p&gt;

+               <description>&lt;p&gt;It is strange to watch how a bug in Debian causing KDM to fail to
+start at boot when an NVidia video card is used is handled.  The
+problem seem to be that the nvidia X.org driver uses a long time to
+initialize, and this duration is longer than kdm is configured to
+wait.&lt;/p&gt;
+
+&lt;p&gt;I came across two bugs related to this issue,
+&lt;a href=&quot;http://bugs.debian.org/583312&quot;&gt;#583312&lt;/a&gt; initially filed
+against initscripts and passed on to nvidia-glx when it became obvious
+that the nvidia drivers were involved, and
+&lt;a href=&quot;http://bugs.debian.org/524751&quot;&gt;#524751&lt;/a&gt; initially filed against
+kdm and passed on to src:nvidia-graphics-drivers for unknown reasons.&lt;/p&gt;
+
+&lt;p&gt;To me, it seem that no-one is interested in actually solving the
+problem nvidia video card owners experience and make sure the Debian
+distribution work out of the box for these users.  The nvidia driver
+maintainers expect kdm to be set up to wait longer, while kdm expect
+the nvidia driver maintainers to fix the driver to start faster, and
+while they wait for each other I guess the users end up switching to a
+distribution that work for them.  I have no idea what the solution is,
+but I am pretty sure that waiting for each other is not it.&lt;/p&gt;
+
+&lt;p&gt;I wonder why we end up handling bugs this way.&lt;/p&gt;
