Am I correct in guessing that Linux does not support SUID?

For example, if I write a script as root like :

#!/bin/sh

/etc/init.d/xinetd restart



and then give it permissions chmod 4755.

Doesn't that mean that any user can then start xinetd? Can anybody clarify this for me.

Thanks.

SUID is supported, but not for shell scripts. This is for security reasons (too easy to exploit to give root access, apparently). I don't know if this can be changed - probably, knowing linux - but the point is that you shouldn't be doing such a thing anyway. If you really need a normal user to run such a command, investigate sudo, or change the permissions on "service".
