Introduction[edit]
Managing runlevels is usually done through the rc-update helper, but could of course be done by hand if desired. e.g. rc-update add nginx default - add nginx to the default runlevel
All runlevels are represented as folders in /etc/runlevels/ with symlinks to the actual service scripts.
All services must reside in the /etc/init.d or /usr/local/etc/init.d directories. They must also conform to the OpenRC runscript standard.
Manual[edit]
NAME
rc-update – add and remove services to and from a runlevel
SYNOPSIS
rc-update [-s, --stack] add service [runlevel ...]
rc-update [-s, --stack] [-a, --all] delete service [runlevel ...]
rc-update [-u, --update] [-v, --verbose] show [runlevel ...]
DESCRIPTION
OpenRC uses named runlevels. Rather than editing some obscure file or managing a directory of symlinks, rc-update exists to quickly add or delete services to and from from different runlevels. All services must reside in the /etc/init.d or /usr/local/etc/init.d directories.
They must also be standard OpenRC scripts, meaning they must use openrc-run.
add service Add the service to the runlevel or the current
one if none given. Services added to the boot
runlevel must exist in /etc/init.d.
delete service Delete the service from the runlevel or the
current one if none given.
show Show all enabled services and the runlevels they
belong to. If you specify runlevels to show,
then only those will be included in the output.
-v, --verbose Show all services.
-u, --update Forces an update of the dependency tree cache.
This may be needed in the event of clock skew (a
file in /etc is newer than the system clock).
If the -s, --stack option is given then we either add or remove the runlevel from the runlevel. This allows inheritance of runlevels.
If the -a, --all option is given, we remove the service from all runlevels. This is useful, for example, to clean up the dangling symlinks after a service is removed.
