Alpine Linux uses OpenRC as init system which has a few configuration option that can be changed. Most options are already explained in the `/etc/rc.conf` file which has to be edited.
If `home-manager` has been initialised and logged into the Wayfire session then it should have started a lot of services automatically. These are created and managed through `home-manager`.
The help and manual pages of runit explain how to use `sv` to manage the services.
