that .sock file is not the same as the /var/run/chrony.yyACM0.sock file.
(And no, I don't think the documentation is very clear on this part.)
For time synchronization, I recommend ensuring gpsd is called with the `-n` flag, and systemd starts it on startup. (This requires modifying the systemd file for this, which includes removing the chrony.ttyXX.sock file, and the dependencies on it.... ) Although the list might have a better way.
1. What OS brand & version are you using?
2. Are you running this on a RPi, or a x86 computer?
I just set this up last week with a serial/pps line + intel computer + gpsd- (3.20 / master) + chrony (2.11). So, it definitely _CAN_ be done, but the setup can be finicky.
