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.

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>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.

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.

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> - Pieces of the roaming laptop puzzle in Debian - http://people.skolelinux.org/pere/blog/Pieces_of_the_roaming_laptop_puzzle_in_Debian.html - http://people.skolelinux.org/pere/blog/Pieces_of_the_roaming_laptop_puzzle_in_Debian.html - Wed, 19 May 2010 19:00:00 +0200 + Skolelinux er laget for sentraldrifting, naturligvis + http://people.skolelinux.org/pere/blog/Skolelinux_er_laget_for_sentraldrifting__naturligvis.html + http://people.skolelinux.org/pere/blog/Skolelinux_er_laget_for_sentraldrifting__naturligvis.html + Wed, 9 Jun 2010 12:30:00 +0200 -<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> - -<p>If you want to help out with implementing this for Debian Edu, -please contact us on debian-edu@lists.debian.org.</p> +<p>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 +<a href="http://www.idg.no/computerworld/article169432.ece">IT-sjef +Viggo Billdal i Steinkjer intervjuet</a>, og forteller uten +blygsel:</p> + +<blockquote><p>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.</p></blockquote> + +<p>En <a +href="https://init.linpro.no/pipermail/skolelinux.no/bruker/2010-June/009101.html">rask +sjekk</a> 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 +<a href="http://www.dn.no/multimedia/archive/00090/Dagens_it_nr__18_90826a.pdf">Dagens +IT nr. 18 2005</a> hvor en kan lese på side 18:</p> + +<blockquote><p>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.</p></blockquote> + +<p>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: + +<blockquote> +<p>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.</p> + +<p>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.</p> + +<p>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.</p> + +<p>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.</p> +</blockquote> + +<p>Jeg vet at Narvik, Harstad og Oslo er kommuner der Skolelinux +sentraldriftes med sentrale tjenere.
