The clock_readonly option is a list of clocks which sfptpd should never synchronize or adjust.

This option can be used, for example, to prevent sfptpd from adjusting the system clock when running alongside chronyd. chronyd in such a configuration will synchronize the system clock.

Usage

clock_readonly [name | mac-address | clock-id | interface]

Specifies a set of clocks that sfptpd should never step or slew, under any circumstance.

Important: Use with care to avoid unexpected behaviors.
