That seems like it would be effective if the goal is to make it impossible for non-root users to do a shutdown / reboot. That wasn't my goal, but apparently what I had in mind is so unusual that there's no reasonable way to accomplish it. What I'm kind of wondering, though, is how any of this helps if users have physical access to the machine's power switch -- and it seems like in the usual setup, these various shutdown/reboot GUI options are only available to someone sitting at the console anyway. There's probably something I'm not getting! -- blm
