NAME¶
openrc
—
stops and starts services for the specified
runlevel
SYNOPSIS¶
openrc |
[ -n ,
--no-stop ]
[-o ,
--override ]
[runlevel ] |
DESCRIPTION¶
openrc
first stops any services that are not
in the specified runlevel unless --no-stop is specified, then starts any
services in the runlevel and stacked runlevels added by
rc-update
that are not currently started.
If no runlevel is specified, we use the current runlevel.
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.
openrc
uses
/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.
- 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.
