FSHALT(8) FSHALT(8)
NAME
fshalt, scram, reboot - halt any local file systems and
optionally shut down or reboot the system
SYNOPSIS
fshalt [ -r ]
reboot [ kernelpath ]
scram
DESCRIPTION
Fshalt syncs and halts all local cwfs(4) and hjfs(4)
servers. If given -r, fshalt will then reboot the machine.
Else it will invoke scram to shut down the machine. The
halting and rebooting is done by copying all necessary com-
mands into a ramfs(4) file system and changing directory
there before attempting to halt file systems, so this will
work even on standalone machines with their roots on local
file systems.
Reboot restarts the machine it is invoked on. If an optional
kernelpath is specified then the machine will load and start
that kernel directly instead of returning to the system rom.
(see cons(3)).
Scram shuts down the machine it is invoked on.

BUGS
On standalone machines, it will be impossible to do anything
if scram fails after invoking bare fshalt.
Scram is limited to the PC and requires APM or ACPI.
