Introduction

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.

Rc-update

rc-update shows all runlevels and services:

boot shows if a service starts at boot.

If you want a service starting at boot write as root:

rc-update add foo .

If a service don't have to start at boot write:

rc-update delete foo.
