OpenRC
OpenRC is a minimal init system. Distributions using OpenRC include Alpine Linux.
Usage
To stop, start, and get the current status of a service, try:
rc-service sshd stop rc-service sshd start rc-service sshd status
To start a service automatically at boot and verify that setting, try:
rc-update add sshd default rc-status
Use the default runlevel for user services. The other runlevels (boot, single, reboot, and shutdown) should be reserved for the operating system.
