Remember, Unix is a multiuser operating system, and also one supporting both local and remote users, who would be annoyed by someone deciding to cut them off. Imagine a host with hundreds of simultaneous users, such as (say) a shared ISP machine. You would absolutely not want just anyone to be able to shutdown or reboot the machine at will. Tberefore, the conventional solution to this problem is to require membership in a bespoke group for shutdown/reboot rights. That being said, although the Linux kernel (like those of other Unix-type OSes) can intercept hardware reboot signals (like Ctrl-Alt-Del on x86) and control/define what that does, generally speaking anyone with physical console access can force reboot one way or another anyway. -- Cheers, « On donne des conseils, mais on ne Rick Moen donne point la sagesse d'en profiter. » r...@linuxmafia.com -- La Rochefoucauld McQ!
