Thanks Eric and Dan.  I will have to build myself a big sandbox when I have a
little more time and test all of this out.  As of now I should probably just
update this server and quit messing around :-)

But I think this would be awesome for the future.  Only hangup I see is
storing the iso images on a separate server.  I wonder if I could keep the
iso's on a separate internal drive and install from there.  That would maybe
eliminate the need to keep up an entirely separate server.  Maybe I could
rsync the iso's on /iso_storage which would be a 10GB internal IDE drive or
something, keep the ks.cfg file under this directory, then call on those ISO's
and ks file locally on reboot.  Hmmm, a lot to think about.
