Yes, kudlge.  For one purpose; 1st time Raspberry Pi users that can't
figure out how to use the command line.

I'm not about to extend the kludge, I want to kill it off.  Just put
"/dev/pps0" on your gpsd command line.

A dead end.  On linux gpsd knows to create and check /dev/pps0.  That is
the code path that needs to be fixed.  Or the code path from the command

I remember there was some commands to run before gpsd that fixed a simila9r
issue on some gpsd's.  Someone needs to check the email archives.

No PPS at all in that log.  So not relevant to our PPS discussion.
