+<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 kontakter. 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 kontakt 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>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>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>
+
+<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>

+<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>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>

+<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 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>

+ <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>
+#!/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
+</pre></blockquote>
+
+<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>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>

-<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>

-<p>A few days ago, parallel booting was enabled in Debian/testing.
-The feature seem to hold up pretty well, but three fairly serious
-issues are known and should be solved:
-
-<p><ul>
-
-<li>The wicd package seen to
-<a href="http://bugs.debian.org/508289">break NFS mounting</a> and
-<a href="http://bugs.debian.org/581586">network setup</a> when
-parallel booting is enabled. No idea why, but the wicd maintainer
-seem to be on the case.</li>
-
-<li>The nvidia X driver seem to
-<a href="http://bugs.debian.org/583312">have a race condition</a>
-triggered more easily when parallel booting is in effect. The
-maintainer is on the case.</li>
-
-<li>The sysv-rc package fail to properly enable dependency based boot
-sequencing (the shutdown is broken) when old file-rc users
-<a href="http://bugs.debian.org/575080">try to switch back</a> to
-sysv-rc. One way to solve it would be for file-rc to create
-/etc/init.d/.legacy-bootordering, and another is to try to make
-sysv-rc more robust. Will investigate some more and probably upload a
-workaround in sysv-rc to help those trying to move from file-rc to
-sysv-rc get a working shutdown.</li>
-
-</ul></p>
-
-<p>All in all not many surprising issues, and all of them seem
-solvable before Squeeze is released. In addition to these there are
-some packages with bugs in their dependencies and run level settings,
-which I expect will be fixed in a reasonable time span.</p>
-
-<p>If you report any problems with dependencies in init.d scripts to
-the BTS, please usertag the report to get it to show up at
-<a href="http://bugs.debian.org/cgi-bin/pkgreport.cgi?users=initscripts-ng-devel@lists.alioth.debian.org">the
-list of usertagged bugs related to this</a>.</p>
-
-<p>Update: Correct bug number to file-rc issue.</p>

- <title>More flexible firmware handling in debian-installer</title>

-<p>After a long break from debian-installer development, I finally
-found time today to return to the project. Having to spend less time
-working dependency based boot in debian, as it is almost complete now,
-definitely helped freeing some time.</p>
-
-<p>A while back, I ran into a problem while working on Debian Edu. We
-include some firmware packages on the Debian Edu CDs, those needed to
-get disk and network controllers working. Without having these
-firmware packages available during installation, it is impossible to
-install Debian Edu on the given machine, and because our target group
-are non-technical people, asking them to provide firmware packages on
-an external medium is a support pain. Initially, I expected it to be
-enough to include the firmware packages on the CD to get
-debian-installer to find and use them. This proved to be wrong.
-Next, I hoped it was enough to symlink the relevant firmware packages
-to some useful location on the CD (tried /cdrom/ and
-/cdrom/firmware/). This also proved to not work, and at this point I
-found time to look at the debian-installer code to figure out what was
-going to work.</p>
-
-<p>The firmware loading code is in the hw-detect package, and a closer
-look revealed that it would only look for firmware packages outside
-the installation media, so the CD was never checked for firmware
-packages. It would only check USB sticks, floppies and other
-"external" media devices. Today I changed it to also look in the
-/cdrom/firmware/ directory on the mounted CD or DVD, which should
-solve the problem I ran into with Debian edu. I also changed it to
-look in /firmware/, to make sure the installer also find firmware
-provided in the initrd when booting the installer via PXE, to allow us
-to provide the same feature in the PXE setup included in Debian
-Edu.</p>
-
-<p>To make sure firmware deb packages with a license questions are not
-activated without asking if the license is accepted, I extended
-hw-detect to look for preinst scripts in the firmware packages, and
-run these before activating the firmware during installation. The
-license question is asked using debconf in the preinst, so this should
-solve the issue for the firmware packages I have looked at so far.</p>
-
-<p>If you want to discuss the details of these features, please
-contact us on debian-boot@lists.debian.org.</p>

-<p>For en stund tilbake kjøpte jeg en magnetkortleser for å kunne
-titte på hva som er skrevet inn på magnetstripene til ulike kort. Har
-ikke hatt tid til å analysere mange kort så langt, men tenkte jeg
-skulle dele innholdet på to kort med mine lesere.</p>
-
-<p>For noen dager siden tok jeg flyet til Harstad og Hurtigruten til
-Bergen. Flytoget fra Oslo S til flyplassen ga meg en billett med
-magnetstripe. Påtrykket finner jeg følgende informasjon:</p>
-
-<pre>
-Flytoget Airport Express Train
-
-Fra - Til : Oslo Sentralstasjon
-Kategori : Voksen
-Pris : Nok 170,00
-Herav mva. 8,00% : NOK 12,59

-Utstedt: : 08.05.10
-Gyldig Fra-Til : 08.05.10-07.11.10
-Billetttype : Enkeltbillett
-
-102-1015-100508-48382-01-08

-
-<p>På selve magnetstripen er innholdet
-<tt>;E?+900120011=23250996541068112619257138248441708433322932704083389389062603279671261502492655?</tt>.
-Aner ikke hva innholdet representerer, og det er lite overlapp mellom
-det jeg ser trykket på billetten og det jeg ser av tegn i
-magnetstripen. Håper det betyr at de bruker kryptografiske metoder
-for å gjøre det vanskelig å forfalske billetter.</p>
-
-<p>Den andre billetten er fra Hurtigruten, der jeg mistenker at
-strekkoden på fronten er mer brukt enn magnetstripen (det var i hvert
-fall den biten vi stakk inn i dørlåsen).</p>
-
-<p>Påtrykket forsiden er følgende:</p>

-<p>Today, the last piece of the puzzle for roaming laptops in Debian
-Edu finally entered the Debian archive. Today, the new
-<a href="http://packages.qa.debian.org/libp/libpam-mklocaluser.html">libpam-mklocaluser</a>
-package was accepted. Two days ago, two other pieces was accepted
-into unstable. The
-<a href="http://packages.qa.debian.org/p/pam-python.html">pam-python</a>
-package needed by libpam-mklocaluser, and the
-<a href="http://packages.qa.debian.org/s/sssd.html">sssd</a> package
-passed NEW on Monday. In addition, the
-<a href="http://packages.qa.debian.org/libp/libpam-ccreds.html">libpam-ccreds</a>
-package we need is in experimental (version 10-4) since Saturday, and
-hopefully will be moved to unstable soon.</p>
-
-<p>This collection of packages allow for two different setups for
-roaming laptops. The traditional setup would be using libpam-ccreds,
-nscd and libpam-mklocaluser with LDAP or Kerberos authentication,
-which should work out of the box if the configuration changes proposed
-for nscd in <a href="http://bugs.debian.org/485282">BTS report
-#485282</a> is implemented. The alternative setup is to use sssd with
-libpam-mklocaluser to connect to LDAP or Kerberos and let sssd take
-care of the caching of passwords and group information.</p>
-
-<p>I have so far been unable to get sssd to work with the LDAP server
-at the University, but suspect the issue is some SSL/GnuTLS related
-problem with the server certificate. I plan to update the Debian
-package to version 1.2, which is scheduled for next week, and hope to
-find time to make sure the next release will include both the
-Debian/Ubuntu specific patches. Upstream is friendly and responsive,
-and I am sure we will find a good solution.</p>
-
-<p>The idea is to set up the roaming laptops to authenticate using
-LDAP or Kerberos and create a local user with home directory in /home/
-when a usre in LDAP logs in via KDM or GDM for the first time, and
-cache the password for offline checking, as well as caching group
-memberhips and other relevant LDAP information. The
-libpam-mklocaluser package was created to make sure the local home
-directory is in /home/, instead of /site/server/directory/ which would
-be the home directory if pam_mkhomedir was used. To avoid confusion
-with support requests and configuration, we do not want local laptops
-to have users in a path that is used for the same users home directory
-on the home directory servers.</p>
-
-<p>One annoying problem with gdm is that it do not show the PAM
-message passed to the user from libpam-mklocaluser when the local user
-is created. Instead gdm simply reject the login with some generic
-message. The message is shown in kdm, ssh and login, so I guess it is
-a bug in gdm. Have not investigated if there is some other message
-type that can be used instead to get gdm to also show the message.</p>

-please contact us on debian-edu@lists.debian.org.</p>
