[Discuss] tcsh, AD, and RHEL 5.6

[gaf at blu.org (Jerry Feldman)]

I think it is a bad practice to symlink (or hardlink) /bin/sh to bash,
especially on a commercial Unix system. Basically, the Bourne Shell and
the BASH shell have different behaviors. You are much, much better off
installing the BASH shell on a commercial Unix system.
