I am running the bash that comes with the distributions, which all
appear to be non bash2.x (which means no -r option, or mention of
rbash), and still my understanding of rsh (the restricted shell I have
used) all you can really do is do better tracking of who runs what and
what they are allowed to run (like with sudo), and does not help in
chrooting a user.  Is this correct in this as well?
