[K12OSN] teaching kids sys admin with VM's

Too bad you can't come across 10 or so adequate computers.  In my
computer repair class, we took our thin clients, installed hard drives
(we had a stack of 6.4 GB), and then installed Ubuntu.  With only a
400 MHz processor and 128 MB RAM it wasn't fast, but they did enjoy
the opportunity.  When they were done, we unplugged the hard drives.

One kid also brought in an OpenSuse CD, but it didn't want to install.
 We've also played with our thin clients and Knoppix.  So long as
these thin clients will boot, they're easy to re-configure to work off
the K12LTSP server.

Good luck.
