RC¶

NAME¶

rc - stops and starts services for the specified runlevel

SYNOPSIS¶

rc [-o , -override ] [runlevel ]

DESCRIPTION
rc first stops any services that are not for the runlevel and then starts any services in the runlevel and from stacked runlevels added by rc-update that are not currently started. If no runlevel is specified then we use the current runlevel the system is currently in.

There are some special runlevels that you should be aware of:

sysinit

Brings up any system specific stuff such as /dev, /proc and optionally /sys for Linux based systems. It also mounts /lib/rc/init.d as a ramdisk using tmpfs where available unless / is mounted rw at boot. rc uses /lib/rc/init.d to hold state information about the services it runs. sysinit always runs when the host first starts and should not be run again.

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.

single

Stops all services except for those in the sysinit runlevel.

reboot

Changes to the shutdown runlevel and then reboots the host.

shutdown

Changes to the shutdown runlevel and then halts the host.

You should not call any of these runlevels yourself. Instead you should use init(8) and shutdown(8) and let them call these special runlevels.
