If possible, I suggest we switch to using LDAP as the source of this
information, and figure out which daemons can provide that.

Here, I propose we switch everyone to OCS inventory, and extend it to
be able to generate munin (and hopefully also nagios) configuration
from it. I wrote sitesummary as a hack to get something working while
we looked at better alternatives. OCS Invetory was (still is?)
missing the server part in Debian Etch, so it was not really an option
for Debian Edu Etch.

The best approach here to figure out what is changed, is to install a
main-server profile and use debian-edu-etc-svk to check out the
configuration changes done related to .intern and 10.0.2.0.

There is basic support for switching desktop from kde to gnome in
debian-edu (the desktop-kde and desktop-gnome subtasks), but it need
more work, and we need to figure out a way to select which one during

This option has been a long term plan, so I suggest we try to
implement it and fall back to option b) when we run out of time. It
is what we have been doing all along, and the system is getting easier
and easier to customize. :)
Another idea I have is to use machine netgroups more actively. Say,
to enable exam mode on a machine it is inserted into the exam-hosts
netgroup and rebooted (or perhaps it dynamically take effect), and
then the machine is locked down for exams. There is a lot we can do
with grouping of machines in netgroups that would make administration
easier. At the moment it is only used for NFS access, but that is
just the start.
