openrc

Change to a specific runlevel

$ sudo openrc [runlevel_name]

$ sudo openrc -n [runlevel_name]

openrc [options] [runlevel]

openrc is the service manager for OpenRC-based systems, providing an alternative to systemd for managing system services and runlevels. It's the default init system on Gentoo, Alpine Linux, and other distributions.
OpenRC uses the concept of runlevels (similar to SysV init) to group services that should run together. Common runlevels include default (normal operation), boot (essential services), single (single-user mode), and shutdown.
Services are managed through scripts in /etc/init.d/ and configured using rc-update to add or remove them from runlevels.

-n, --no-stop

Don't stop any services when changing runlevels

Override the next runlevel to go to when leaving single user

Run the service specified with the rest of the arguments

Run the service as if in /etc/init.d

Runlevel changes may stop services in the current runlevel that aren't in the target. Use -n to preserve running services. OpenRC is not compatible with systemd; distributions use one or the other.
