I went across a fair bit of this ground back in December. one of the
issues I found was that I needed to put root as the first drive on the

Edubuntu-desktop should add the extra software and packages to give you a
desktop edubuntu system. Depending on whether you want Edubuntu as a thin
client server, you may need to install the package edubuntu-server and do

Ouch. That's odd. What error do you get when you try these?
If aptitude crashed, which it apparently did, there may be some partially
installed packages hanging around. These must be installed fully before
you can do anything else. Usually apt would prompt you to do so but if you
haven't already you might need to do:
sudo dpkg --configure -a
to tell it finish off any half-installed packages.

Having done the above, I think you should be able to do
sudo aptitude remove edubuntu-desktop
sudo aptitude autoremove
to remove the overall package and then remove the packages which came in
with it. I _think_ that'll work.

I think you have the right way already (perhaps adding the edubuntu-server
package too). It's certainly what I did. The segmentation fault is very
unusual and not caused by you doing something incorrect.

I can't give you an answer on this. However, reliability issues such as
software RAID among others will hopefully be discussed at the next Ubuntu
Education Summit in the meeting "Making Edubuntu More Fault Tolerant /
Recoverable". If you have something to add you can either come along if
possible or mention it here and I'll be there to pass on your thoughts.
