I'm not going to verify this right now but I believe "buz" can execute 
the command "poweroff" to shutdown -h now
and "reboot" to shutdown -r now.

        [rj at mavis rj]$ ls -l `which poweroff`
        lrwxrwxrwx 1 root root 13 Apr 2 2009 /usr/bin/poweroff ->
        consolehelper
        [rj at mavis rj]$ ls -l `which reboot`
        lrwxrwxrwx 1 root root 13 Apr 2 2009 /usr/bin/reboot ->
        consolehelper
        [rj at mavis rj]$
