This is *very* odd, that users are created using sh, which is supposed to
resemble the original Bourne shell. It has far fewer capabilities than any
of the later shells, and I have no idea why you'd want users screwing with
that. It's very much *not* used much any more....
I'd change all users in /etc/password to bash, unless they've explicitly
requested something else - (t)csh, or zed, whatever.
