.Sh NAME
|
|
.Nm rc
|
|
.Nd stops and starts services for the specified runlevel
|
|
.Sh SYNOPSIS
|
|
.Nm
|
|
.Op Fl o , -override
|
|
.Op Ar runlevel
|
|
.Sh DESCRIPTION
|
|
.Nm
|
|
first stops any services that are not for the runlevel and then starts any
|
|
services added by
|
|
.Nm rc-update
|
|
that are not currently started. If no runlevel is specified then we use the
|
|
current runlevel the system is currently in.
|
|
.Pp
|
|
There are some special runlevels that you should be aware of:
|
|
.Bl -tag -width "shutdown"
|
|
.It Ar sysinit
|
|
Brings up any system specific stuff such as
|
|
.Pa /dev ,
|
|
.Pa /proc
|
|
and optionally
|
|
.Pa /sys
|
|
for Linux based systems. It also mounts
|
|
.Pa /lib/rc/init.d
|
|
as a ramdisk using tmpfs where available unless / is mounted rw at boot.
|
|
.Nm
|
|
uses
|
|
.Pa /lib/rc/init.d
|
|
to hold state information about the services it runs.
|
|
sysinit always runs when the host first starts should not be run again.
|
|
.It Ar boot
|
|
Generally the only services you should add to the boot runlevel are those
|
|
which deal with the mounting of filesystems, set the initial state of attached
|
|
peripherals and logging.
|
|
Hotplugged services are added to the boot runlevel by the system.
|
|
All services in the boot and sysinit runlevels are automatically included
|
|
in all other runlevels except for those listed here.
|
|
.It Ar single
|
|
Stops all services except for those in the sysinit runlevel.
|
|
.It Ar reboot
|
|
Changes to the shutdown runlevel and then reboots the host.
|
|
.It Ar shutdown
|
|
Changes to the shutdown runlevel and then halts the host.
|
|
.El
|
|
.Pp
|
|
You should not call any of these runlevels yourself.
|
|
Instead you should use
|
|
.Xr init 8
|
|
and
|
|
.Xr shutdown 8
|
|
and let them call these special runlevels.
