Void Linux uses runit
All available services in /etc/sv
See below re /var/service/ - running services?
Enabled services in /etc/runit/runsvdir (via links to /etc/sv/..)

'll /var/service/' should show running services

# sv up <services>
# sv down <services>
# sv restart <services>
# sv status <services>

Enabling Services

Void Linux provides service directories for most daemons in /etc/sv/.

To enable a service on a booted system, create a symlink to the service directory in /var/service/:

# ln -s /etc/sv/<service> /var/service/

If the system is not currently running, the service can be linked directly into the default runsvdir:

# ln -s /etc/sv/<service> /etc/runit/runsvdir/default/

This will automatically start the service.
 Once a service is linked it will always start on boot and restart if it stops,
 unless administratively downed.

To prevent a service from starting at boot while allowing runit to manage it,
 create a file named down in its service directory:

# touch /etc/sv/<service>/down
