+Title: How to transform a Debian based system to a Debian Edu installation
+Tags: english, debian edu, debian

+<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 <ahref="http://www.raspberrypi.org">Raspberry Pi</a> as a
+Debian Edu client, and using it he can take the existing
+<ahref="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 Gnome 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="gnome"
+</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>
