Hi Gary.

Good point. I've smartened up my udev rules to handle all the current variants. One thing - gpsd doesn't seem to like PPS devices that aren't named /dev/ppsN. Is that the case?
Thanks,

-Nick

 I believe that I can simply list (on the gpsd command line) the two
 potential GPS devices, and follow them with the PPS device, and gpsd
 and ntpd will not be bothered by the fact that one GPS device never
 reports any data.

Or, the tradictional solution, is for each system to have a link (/dev/gps0)
to the active GPS device.  That way the client tools can also be the
same for each system.  "cgps ::/dev/gps0", vs "cgps ::/dev/XX" and
"cgps ::/dev/YY".
