That's weird. Theoretical cold start is 40seconds w/o A-GPS, with
A-GPS it should take lock in few seconds. Anyway, I'm trying to get
gpsd working with gnss-share/geoclue, not solve A-GPS.

Clayton knows this and he answered that IIRC.

Ok, I'll try to gather them. But note that it is going to be PinePhone
and Librem 5 support, and what I'm trying to accomplish at the moment
is gnss-share support :-).
