no, you need this:

	NAME
 	      	halt, reboot, poweroff - stop the system.

	SYNOPSIS
       		/sbin/halt [-n] [-w] [-d] [-f] [-i] [-p] [-h]
       		/sbin/reboot [-n] [-w] [-d] [-f] [-i]
       		/sbin/poweroff [-n] [-w] [-d] [-f] [-i] [-h]

also:

	NAME
	       	shutdown - bring the system down

	SYNOPSIS
       		/sbin/shutdown [-t sec] [-arkhncfF] time [warning-message]

but that's not all! you are also required to have the usermode utilities. To quote:

	The usermode package contains the userhelper program, which
	can be used to allow configured programs to be run with
	superuser privileges by ordinary users.

It provides, among other things, the very user-helpful:

	/usr/bin/halt
	/usr/bin/poweroff
	/usr/bin/reboot

which allow a normal user to reboot the console without having
administrative privileges!

You may say "but why don't you just remove the usermode package, eh?"

The answer is hidden here, try to find it:

root@fbsd# rpm -ev usermode
error: Failed dependencies:
        usermode is needed by (installed) redhat-config-proc-0.18-1
        usermode >= 1.36 is needed by (installed) redhat-config-securitylevel-1.0.1-1

root@fbsd#


Now, the $0.02 question is: "Can you guess which of the two 'reboot'
programs, the one that wants root, and the one that doesn't, comes
first in a default RedHat user's $PATH?"

ps: I had to run sed on this email to change all the '-' in the pasted
man pages from the special short dash symbol that Red Hat uses, surely
to prevent me from searching for documentation on specific options by
typing '/-d' for example.

pps: I'm sending this email as a pissed off FreeBSD user, not as a
pissed off Plan 9 user.  Plan 9 is so detached from such debaucheries,
that their vile nature is incomprehensible to the average 9fan, thus
cannot drive him (her) to such curmudgeonry as witnessed in this
email.
