See also http://www.redwoodvirtual.com.  They offer root accounts in a
UML environment.  I don't work for them nor am I a customer.  Though I
am thinking of playing with the idea in case I wanted to venture into
web hosting.  I'm always up for learning something new anyway!

I was a bit ambiguous earlier in the thread when I said "virtual
environment."  My main goal would be to run Linux on Linux, as close to
hardware as I can get for the purpose of testing other Linux distributions.  
Recently I installed several Linux distros to get screenshots of how to 
update that specific distro.  I used spare space on my hard drive for
the installs, but then I had to worry about uids and gids and mounting
the other partitions correctly so I could save off the screenshots.  Not
a big deal, but if I am going do more of this, I'd like to run the
distros as a VM and mount /home via NFS, and authenticate via
OpenLDAP+PAM.
