[LinuxPPS] chrony with LinuxPPS and gpsd

[Remco dB]

Miroslav,

I want to test it on a system which is fed by a PPS signal, locked to UTC 
epochs. So, in ntpd terms: I only need an external (internet) reference and 
driver 22 (127.127.22.0).

Therefore I do not need the gpsd part. 

How do I need to config chrony in that case?

Afterwards, is chronyd 'ntpdc-able' ? I.e. are ntpdc queries like
ntpdc -c kern <host> possible?

Regards,
Remco
