Ahhh, sorry to confuse you more with 'sudo'. On my system, I can't
run 'chroot' as a user; that is, I can execute it, but it says
"Operation not permitted", so I used the sledgehammer of root.
What sudo basically does is run the given command with root
permissions; it's similar to "su root -c ...", only you don't have
to know the root password.  So, try just removing the 'sudo' part
of all the commands I gave.

As far as the prompt goes, that's probably bash setting up the
prompt, and trying to run "whoami" or something similar, as well
as 'uname -n'.  Either it already knew the server name, or
something, because that came through; "whoami" didn't
(correctly). Copy that executable into the chroot and the problem
should go away.

Never underestimate the bandwidth of a station wagon full of tapes.
