Re: [gpsd-users] gpsd not capturing device on startup

[Joshua Quesenberry]

Is running `/usr/sbin/gpsd` sufficient for it to auto-magic everything else?
Or do I need to run it like `/usr/sbin/gpsd -N -n -F /var/run/gpsd.sock
/dev/ttyACM0` ? I read that it can dynamically add/remove devices?

Ah, don't do that.  gpsd does not run well from systemd.  remove what ever
way your distribution starts up gpsd and do it yourself with a simple
script.

cgps is your friend.  Do not fear it.  Or start gpsd in debug mode.

Once again, systemd is messing with your head.  Rip out the systemd stuff
and start gpsd manually.
