very weird... and, since you made the files world writable, are the
files actually changed?

try `xterm -e /bin/bash`

it happens because jk_chrootsh is your shell. However, what is the shell
in your jail in <jail>/etc/passwd ?

if you are running nscd you can stop it and see if that solves the
problem. (if xterm asks nscd for the shell to use it will return the
shell in the real /etc/passwd, which is jk_chrootsh and not a real
shell. If xterm cannot use nscd it will look in <jail>/etc/passwd for
your shell)

jk_chrootsh is not a normal shell, it does a chroot() call and executes
your real shell. So you do not need in inside your jail, and it is not
useful inside a jail either.

`man jk_chrootsh`
