I realize that, but ``shutdown -r now'' is just as final (and
instantaneous) as ``reboot'' yet mere mortals are permitted to use
it (assuming they are members of the group wheel). Surely, from a
security point of view, only one user (root) should be able to
halt/reboot a machine; or are all members of wheel supposed to be
intelligent, considerate (towards other users) individuals?
