Way cool!  We've to tons of boxes that are a complete pain is the ass to
install on via CD, this will save tons of time.  Obviously, it would be
better it we made one of these as part of the release build and put it
on the ftp site, but this is a hugh step in the right direction.

One minor nit, you might want to put a check that the user is root at the
top of the script since that is a requirement.
