Since the switch to systemd, the udev configuration needs to be reworked
to work properly both for hot and cold plugging.
The Fedora maintainers have kindly shared their solution here:
https://lists.gnu.org/archive/html/gpsd-users/2014-04/msg00037.html
The attached patch introduces a gpsdctl systemd service, which replaces
the hotplug wrapper script. I have successfuly tested the patch with
real hardware:
- booting without a GPS attached, and plugging in the GPS once the
system is started
- booting with a GPS attached
Cheers,
Jeremy
