Shell scripts probably -- HOPEFULLY -- cannot be suid/sgid.  ALLOWING SETUID
SHELL SCRIPTS IS A SECURITY HOLE.  It's notable that Berkeley itself has
sent out a "mandatory" BSD patch which disables setuid on "#!" executables.

On the other hand, your Sun-blinded friend is probably incurable.  [ 1/2 ;-) ]
