It's /bin/sh. It would normally be a good idea for this to be
Bourne-compatible, but I really doubt that matters in your situation. If I had
to make loginfo work in a jail, I'd break my task into two pieces:
1. Get it working using the ash shell... its tiny, mostly bourne- and
POSIX-compliant, and can easily be statically linked.
2. Once that is working reliably, attempt to customize smrsh, rcsh or a
similar restricted shell for my setup.
HTH,
