-<p>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.</p>

+ <description><p>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
+<a href="http://luma.sourceforge.net/">LUMA</a>, 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. :)</p>
-<p>I came across two bugs related to this issue,
-<a href="http://bugs.debian.org/583312">#583312</a> initially filed
-against initscripts and passed on to nvidia-glx when it became obvious
-that the nvidia drivers were involved, and
-<a href="http://bugs.debian.org/524751">#524751</a> initially filed against
-kdm and passed on to src:nvidia-graphics-drivers for unknown reasons.</p>
+<p>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.</p>
-<p>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.</p>
+<p>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
+<a href="http://www.lichteblau.com/ldapvi/">ldapvi</a> for that.</p>
-<p>I wonder why we end up handling bugs this way.</p>
+<p>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.</p>
+
+<p>Update 2010-06-29: Ross Reedstrom tipped us about the
+<a href="http://packages.qa.debian.org/g/gq.html">gq</a> 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.</p>

+ <description><p>A while back, I
+<a href="http://people.skolelinux.org/pere/blog/Time_for_new__LDAP_schemas_replacing_RFC_2307_.html">complained
+about the fact</a> 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.</p>
-<p>Mon tro hva toglinje mellom Narvik og Tromsø ville hatt slags
-effekt på området der?</p>
+<p>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.</p>
+
+<p>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.</p>
+
+<p>Anyway, for future reference, this is how I believe we could change
+the
+<a href="http://tools.ietf.org/html/draft-ietf-dhc-ldap-schema-00">DHCP
+schema</a> to solve at least part of the problem with the LDAP schemas
+available today from IETF.</p>

-<p>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:</p>
+ <title>Calling tasksel like the installer, while still getting useful output</title>
+ <link>http://people.skolelinux.org/pere/blog/Calling_tasksel_like_the_installer__while_still_getting_useful_output.html</link>

+ <pubDate>Wed, 16 Jun 2010 14:55:00 +0200</pubDate>
+ <description><p>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:
<blockquote><pre>
-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
</pre></blockquote>
-<p>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.</p>
+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.
-<p>A larger list is
-<a href="http://narvikskolen.no/sitesummary/">available from the the
-city of Narvik</a>, 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.</p>
+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:
+
+<blockquote><pre>
+export DEBIAN_FRONTEND=noninteractive
+cmd="$(in_target tasksel -t --new-install | sed 's/debconf-apt-progress -- //')"
+$cmd
+</pre></blockquote>
+
+<p>The content of $cmd is typically something like "<tt>aptitude -q
+--without-recommends -o APT::Install-Recommends=no -y install
+~t^desktop$ ~t^gnome-desktop$ ~t^laptop$ ~pstandard ~prequired
+~pimportant</tt>", 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.</p>
+
+<p>A better approach is probably to extend tasksel to be able to
+install packages without using debconf-apt-progress, for use cases
+like this.</p>

+ <description><p><a href="http://www.dagbladet.no/2010/06/16/nyheter/innenriks/streik/arbeidsliv/12157858/">Dagbladet
+melder</a> at Vinmonopolet med bakgrunn i vekterstreiken som pågår i
+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.</p>
+
+<p><a href="http://www.lovdata.no/all/tl-19850524-028-003.html#14">Paragrafen
+i sentralbankloven</a> lyder:</p>
+
+<blockquote>
+<p>§ 14. Tvungent betalingsmiddel</p>
+
+<p>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.</p>
+
+<p>Sterkt skadde sedler og mynter er ikke tvungent
+betalingsmiddel. Banken gir nærmere forskrifter om erstatning for
+bortkomne, brente eller skadde sedler og mynter.</p>
+
+<p>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.</p>
+</blockquote>
+
+<p>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.</p>

-<p>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.</p>

+ <description><p>For those of us caring about document exchange and
+interoperability, <a href="http://www.officeshots.org/">OfficeShots</a>
+is a great service. It is to ODF documents what
+<a href="http://browsershots.org/">BrowserShots</a> is for web
+pages.</p>
-<p>With upstart, I notice these environment variables are set when a
-script is started from rcS.d/ (ignoring some irrelevant ones like
-COLUMNS):</p>
+<p>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.</p>
-<blockquote><pre>
-DEFAULT_RUNLEVEL=2
-previous=N
-PREVLEVEL=
-RUNLEVEL=
-runlevel=S
-UPSTART_EVENTS=startup
-UPSTART_INSTANCE=
-UPSTART_JOB=rc-sysinit
-</pre></blockquote>
+<p>Today I had a look, and was happy to see that the Dell box in our
+machine room now is the host for several virtual machines running as
+OfficeShots factories, and the project is able to render ODF documents
+in 17 different document processing implementation on Linux and
+Windows. This is great.</p>

+ <description><p>My
+<a href="http://people.skolelinux.org/pere/blog/Automatic_upgrade_testing_from_Lenny_to_Squeeze.html">testing
+of Debian upgrades</a> from Lenny to Squeeze continues, and I've
+finally made the upgrade logs available from
+<a href="http://people.skolelinux.org/pere/debian-upgrade-testing/">http://people.skolelinux.org/pere/debian-upgrade-testing/</a>.
+I am now testing dist-upgrade of Gnome and KDE in a chroot using both
+apt and aptitude, and found their differences interesting. This time
+I will only focus on their removal plans.</p>
-<p>With sysvinit, these environment variables are set for the same
-script.</p>
+<p>After installing a Gnome desktop and the laptop task, apt-get wants
+to remove 72 packages when dist-upgrading from Lenny to Squeeze. The
+surprising part is that it want to remove xorg and all
+xserver-xorg-video* drivers. Clearly not a good choice, but I am not
+sure why. When asking aptitude to do the same, it want to remove 129
+packages, but most of them are library packages I suspect are no
+longer needed. Both of them want to remove bluetooth packages, which
+I do not know. Perhaps these bluetooth packages are obsolete?</p>
+
+<p>For KDE, apt-get want to remove 82 packages, among them kdebase
+which seem like a bad idea and xorg the same way as with Gnome. Asking
+aptitude for the same, it wants to remove 192 packages, none which are
+too surprising.</p>
+
+<p>I guess the removal of xorg during upgrades should be investigated
+and avoided, and perhaps others as well. Here are the complete list
+of planned removals. The complete logs is available from the URL
+above. Note if you want to repeat these tests, that the upgrade test
+for kde+apt-get hung in the tasksel setup because of dpkg asking
+conffile questions. No idea why. I worked around it by using
+'<tt>echo >> /proc/<em>pidofdpkg</em>/fd/0</tt>' to tell dpkg to
+continue.</p>

+ <description><p>Veldig glad for å oppdage via
+<a href="http://yro.slashdot.org/story/10/06/11/1841256/Finland-To-Legalize-Use-of-Unsecured-Wi-Fi">Slashdot</a>
+at folk i Finland har forstått at åpne trådløsnett er et samfunnsgode.
+Jeg ser på åpne trådløsnett som et fellesgode på linje med retten til
+ferdsel i utmark og retten til å bevege seg i strandsonen. Jeg har
+glede av åpne trådløsnett når jeg finner dem, og deler gladelig nett
+med andre så lenge de ikke forstyrrer min bruk av eget nett.
+Nettkapasiteten er sjelden en begrensning ved normal browsing og enkel
+SSH-innlogging (som er min vanligste nettbruk), og nett kan brukes til
+så mye positivt og nyttig (som nyhetslesing, sjekke været, kontakte
+slekt og venner, holde seg oppdatert om politiske saker, kontakte
+organisasjoner og politikere, etc), at det for meg er helt urimelig å
+blokkere dette for alle som ikke gjør en flue fortred. De som mener
+at potensialet for misbruk er grunn nok til å hindre all den positive
+og lovlydige bruken av et åpent trådløsnett har jeg dermed ingen
+forståelse for. En kan ikke la eksistensen av forbrytere styre hvordan
+samfunnet skal organiseres. Da får en et kontrollsamfunn de færreste
+ønsker å leve i, og det at vi har et samfunn i Norge der tilliten til
+hverandre er høy gjør at samfunnet fungerer ganske godt. Det bør vi
+anstrenge oss for å beholde.</p>

+ <guid isPermaLink="true">http://people.skolelinux.org/pere/blog/Automatic_upgrade_testing_from_Lenny_to_Squeeze.html</guid>
+ <pubDate>Fri, 11 Jun 2010 22:50:00 +0200</pubDate>
+ <description><p>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
+(<a href="http://bugs.debian.org/585410">#585410</a> in nagios3-cgi,
+<a href="http://bugs.debian.org/584879">#584879</a> already fixed in
+enscript and <a href="http://bugs.debian.org/584861">#584861</a> in
+kdebase-workspace-data), and to get a more regular testing going on, I
+am working on a script to automate the test.</p>
+
+<p>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).</p>
+
+<p>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
+<a href="http://bugs.debian.org/566000">#566000</a> 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
+<a href="http://www.linuxquestions.org/questions/debian-26/failed-dist-upgrade-due-to-udev-config_sysfs_deprecated-nonsense-804130/">known
+issue</a> 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.</p>
+
+<p>Anyway, back to the task at hand, testing upgrades. This test
+script, which I call <tt>upgrade-test</tt> for now, is doing the
+trick:</p>
<blockquote><pre>
-INIT_VERSION=sysvinit-2.88
-previous=N
-PREVLEVEL=N
-RUNLEVEL=S
-runlevel=S
+#!/bin/sh
+set -ex
+
+if [ "$1" ] ; then
+ desktop=$1
+else
+ desktop=gnome
+fi
+
+from=lenny
+to=squeeze
+
+exec &lt; /dev/null
+unset LANG
+mirror=http://ftp.skolelinux.org/debian
+tmpdir=chroot-$from-upgrade-$to-$desktop
+fuser -mv .
+debootstrap $from $tmpdir $mirror
+chroot $tmpdir aptitude update
+cat > $tmpdir/usr/sbin/policy-rc.d &lt;&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 > $tmpdir/usr/lib/tasksel/tests/$test &lt;&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 > $tmpdir/etc/apt/sources.list
+chroot $tmpdir aptitude update
+touch $tmpdir/etc/udev/kernel-upgrade
+chroot $tmpdir aptitude -y dist-upgrade
+fuser -mv

+<p>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</p>
-<p>For scripts needing to behave differently when upstart is used,
-looking for the UPSTART_JOB environment variable seem to be a good

+<p>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</p>
+
+<p>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.</p>

+ <description><p>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.</p>
+
+<p>With upstart, I notice these environment variables are set when a
+script is started from rcS.d/ (ignoring some irrelevant ones like
+COLUMNS):</p>
+
+<blockquote><pre>
+DEFAULT_RUNLEVEL=2
+previous=N
+PREVLEVEL=
+RUNLEVEL=
+runlevel=S
+UPSTART_EVENTS=startup
+UPSTART_INSTANCE=
+UPSTART_JOB=rc-sysinit
+</pre></blockquote>
+
+<p>With sysvinit, these environment variables are set for the same
+script.</p>
+
+<blockquote><pre>
+INIT_VERSION=sysvinit-2.88

+ <description><p>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:</p>
+
+<blockquote><pre>
+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:~#
+</pre></blockquote>
+
+<p>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.</p>
+
+<p>A larger list is
+<a href="http://narvikskolen.no/sitesummary/">available from the the
+city of Narvik</a>, 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.</p>

+ <description><p>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.</p>
+
+<p>I came across two bugs related to this issue,
+<a href="http://bugs.debian.org/583312">#583312</a> initially filed
+against initscripts and passed on to nvidia-glx when it became obvious
+that the nvidia drivers were involved, and
+<a href="http://bugs.debian.org/524751">#524751</a> initially filed against
+kdm and passed on to src:nvidia-graphics-drivers for unknown reasons.</p>
+
+<p>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.</p>
+
+<p>I wonder why we end up handling bugs this way.</p>
