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), hjfs(4), venti(8), and kfs(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 commands 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.
HISTORY
Scram first appeared in 9front (May, 2011).
