Which is why gpsd drops root quickly.

I'm sure there is, but the current scheme is required by ntpd design.

So talk to those ntpd guys and get them to fix it...

I'm also pretty sure that setting the system clock requires root.  You
dont want just any old user to be able to set your clock, right?

Then, there are so many weird ways to set permissions on tty's that
we'd need to right a book on how to fix every variant to run gpsd
as non-root.

As I said 'no working way'.  As currently documented the GPSD_JSON driver
is broken.
