Proposal of new group

[Tomasz Wêgrzanowski <maniek@beer.com>]

I suggest a new group `power'
and setting privileges of shutdown and halt (reboot is symlink to halt) to:
-rwsr-xr--   1 root     power        6876 Jan 12  1999 /sbin/halt
-rwsr-xr--   1 root     power       13492 Jan 12  1999 /sbin/shutdown
(chmod u+s)(chmod o-x)(chown root.power)
This group would be very useful for desktop machines for people who
set computer on (via switch), login as common user and do what they have to
and then stop the computer via command (`halt' or `shutdown -h now')
or via it's interface gshutdown. Now this problem is lacally solved inelegantly
by sudo or by special root account called ex: halt (shell=/sbin/halt) or
by even less secure methods because of lack of the standard.
