[ntp:questions] ntpd connect gpsd shared memory driver

[Rob]

You also need to wait a bit longer before giving up, especially when
you have been frantically changing things and restarting the different
daemons (but not the entire system).

ntpd does not like that.

I think with kernel pps you somewhere have to define what line is
to be used for the pps.  Some specification of a tty device and a
line (e.g. DCD).  I don't remember how it works exactly.  However,
for testing with gpsd it seems best to remove that definition for now.
