The SUID bit does not work on scripts under Linux. This is not a bug,
but a design choice. As for some programs not being tolerant of running
SUID, unless a program is designed to be run this way, you can introduce
security problems when setting a program to run as another user. All
too often, it is possable to gain access as the other user. Any program
that allows shell access definitly should NOT be run SUID!
