Non-su halt?

[D. N. Edwards]

I have a couple of machines going on a road trip soon.  I'd like to know
if there's an easy way to allow non-su users to 'halt' the machines.  I've
changed group protections on halt and init, but I always get the error
"Init: can't idle init."  We're running SunOS 4.0.3.  Any tips
appreciated!

[[Ed's Note: Of course, you could always make halt owned by root, and run
setuid, but I wouldn't recommend this - it's a real security hole. -bdg]]
