Most systems will not permit shell scripts to execute 'setuid'.
Works for me... (TM). (Note the euid...)
Well, well, well, ....
It'll take me a while to figure this one out. Seems that bash and sh
have somewhat different behaviors:
$ cat foo.sh
#!/bin/sh
id
ps -utp1
$ cat bar.sh
#!/bin/bash
id
ps -utp1
$ls -l *.sh
-r-sr-xr-x 1 root staff 24 13 Dec 22:01 bar.sh
-r-sr-xr-x 1 root staff 22 13 Dec 22:00 foo.sh
$ foo.sh

Looks to me like there is either a compatibility issue at play, or a
bug in the system somewhere...
'tcsh' and 'bash' behave the same: scripts can't execute as setuid
root. For 'sh', it appears they can...weird.
Thanks for digging in further...
Regards,
Justin
