I have a shell script that monitors hardware stuff - it needs to run as

As you probably already know, the system won't run shell scripts as setuid,
even if the setuid bit is set. So, the direct route is out.

What is the quickest and simplest solution to this?

 
My gut reaction would be to have the webserver use sudo(1) (with suitable
limitations set in the /etc/sudoers file) to run the script via a system(3)
call.
 

cant one execute it direct from apache?

If it's a shell script then it won't run as root even if it is suid
root.

I'd go the sudo way, but I'm not neutral about that¹.
