. /lib/lsb/init-functions

(Which should be near the top of your init script already.)
This will automagically invoke systemd or upstart if appropriate.
If I understand correctly, OpenRC doesn't require init to directly
start services, so on an OpenRC system your script should run in
the same way it does now.
