Gpsd on HAOS

I’m a few weeks into my HAOS adventure on dedicated hardware. I dug a NaviLock NL-442U out of a drawer. In the web UI, I found gpsd listed as an integration. Trying to install it points me to GPSD - Home Assistant

So I get console access, but neither apt-get nor dnf is installed. Then I learn HAOS runs Alpine Linux and use ‘apk add gpsd’ to install the package. Now I want to start gpsd. It seems OpenRC is not available?

How do I get gpsd to autostart?
