openrc — stops and starts services for the specified runlevel
openrc [-n, --no-stop] [-o, --override] [runlevel]
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.
rc-status(8), rc-update(8), init(8), shutdown(8)
