+ <description><p><a href="http://www.skolelinux.org/">Debian Edu / Skolelinux</a> is
+an operating system based on Debian intended for use in schools. It
+contain a turn-key solution for the computer network provided to
+pupils in the primary schools. It provide both the central server,
+network boot servers and desktop environments with heaps of
+educational software. The project was founded almost 12 years ago,
+2001-07-02. If you want to support the project, which is in need for
+cash to fund developer gatherings and other project related activity,
+<a href="http://www.linuxiskolen.no/slxdebianlabs/donations.html">please
+donate some money</a>.
+
+<p>A topic that come up again and again on the Debian Edu mailing
+lists and elsewhere, is the question on how to transform a Debian or
+Ubuntu installation into a Debian Edu installation. It isn't very
+hard, and last week I wrote a script to replicate the steps done by
+the Debian Edu installer.</p>
+
+<p>The script,
+<a href="http://anonscm.debian.org/viewvc/debian-edu/branches/wheezy/debian-edu-config/share/debian-edu-config/tools/debian-edu-bless?view=markup">debian-edu-bless<a/>
+in the debian-edu-config package, will go through these six steps and
+transform an existing Debian Wheezy or Ubuntu (untested) installation
+into a Debian Edu Workstation:</p>
+
+<ol>
+
+<li>Add skolelinux related APT sources.</li>
+<li>Create /etc/debian-edu/config with the wanted configuration.</li>
+<li>Install debian-edu-install to load preseeding values and pull in
+ our configuration.</li>
+<li>Preseed debconf database with profile setup in
+ /etc/debian-edu/config, and run tasksel to install packages
+ according to the profile specified in the config above,
+ overriding some of the Debian automation machinery.</li>
+<li>Run debian-edu-cfengine-D installation to configure everything
+ that could not be done using preseeding.</li>
+<li>Ask for a reboot to enable all the configuration changes.</li>
+
+</ol>
+
+<p>There are some steps in the Debian Edu installation that can not be
+replicated like this. Disk partitioning and LVM setup, for example.
+So this script just assume there is enough disk space to install all
+the needed packages.</p>
+
+<p>The script was created to help a Debian Edu student working on
+setting up <a href="http://www.raspberrypi.org">Raspberry Pi</a> as a
+Debian Edu client, and using it he can take the existing
+<a href="http://www.raspbian.org/">Rapbian</a> installation and
+transform it into a fully functioning Debian Edu Workstation (or
+Roaming Workstation, or whatever :).</p>
+
+<p>The default setting in the script is to create a KDE Workstation.
+If a LXDE based Roaming workstation is wanted instead, modify the
+PROFILE and DESKTOP values at the top to look like this instead:</p>
+
+<p><pre>
+PROFILE="Roaming-Workstation"
+DESKTOP="lxde"
+</pre></p>
+
+<p>The script could even become useful to set up Debian Edu servers in
+the cloud, by starting with a virtual Debian installation at some
+virtual hosting service and setting up all the services on first
+boot.</p>

- <description><p>For en stund tilbake gikk nyheten om
-<a href="http://en.wikipedia.org/wiki/Sandy_Island,_New_Caledonia">Sandy
-Island</a>, en øy som var dukket opp på noen kart, men som ikke var
-synlig når en sjekket den på satellittbilder. Dagbladet meldte for
-eksempel at
-«<a href="http://www.dagbladet.no/2012/11/22/nyheter/google_maps/google/utenriks/internett/24496816/">denne
-øya finnes på kart, men ikke i virkeligheten</a>». Noe senere begynte
-jeg å lese
-<a href="http://www.gyldendal.no/Barn-og-ungdom/3-6-aar/Den-store-Ruffen-boken">historier
-om Ruffen</a> til mine barn. Dette er historier om sjøormen Ruffen
-skapt av Tor Åge Bringsværd, som starter med følgende beskrivelse:</p>
-
-<p><blockquote>
-«Langt ute i havet ligger en mystisk øy. Den er bare synlig hver
-tirsdag og fredag. Derfor står den ikke på noe kart. På denne øya
-ligger et slott, og i slottet bor en gammel, fin sjøormfamilie.»
-</blockquote></p>
-
-<p>Det virker åpenbart at Hr. Bringsværd tok feil når han trodde den
-ikke var på noe kart, og at noen tydeligvis har vært i nærheten en
-tirsdag eller en fredag og fått den med på et kart, mens
-satellittbildene er tatt på noen av de fem andre dagene i uka og
-dermed ikke ser øya. :)</p>
-
-<p>I følge
-<a href="http://www.dagbladet.no/2012/12/03/nyheter/sandy_island/forskning/utenriks/24662158/">en
-senere artikkel i Dagbladet</a> hevder Shaun Higgins, en forsker fra
-New Zealand, at et hvalfangstskip fra 1876 er opprinnelsen til at
-spøkelsesøya i det hele tatt havnet på kartet. Det fremgår ikke fra
-historien hvilken ukedag de var innom.</p>
-
-<p>Jeg har stor sans for Tor Åge Bringsværd. Og han viste nylig en
-svært fin side av seg selv da han sa ja til EFNs forespørsel om å gi
-ut novellen <a href="http://www.efn.no/kodemus/">Kodémus</a> med
-Creative Commons-lisens.</p>
