Package: chrony
Version: 4.3.2+deb12u1
Severity: important
In investigating an issue in which dhclient got killed prematurely
shortly after boot, resulting in the loss of network connectivity one
lease time later (this motivates the severity), I found that
/etc/network/if-up.d/chrony
doesn't guard against the possibility that "chronyc onoffline" might
return non-zero.
This is indeed what happened in at least one instance, as shown by the
following process accounting records:

On this machine, /etc/network/if-up.d/ contains 000resolvconf, chrony,
ethtool, nslcd, postfix, resolved. Notice how run-parts exits after
chrony. Also notice the exit code (1) of chronyc.
I suspect this is due to /run/chrony/chronyd.pid being created before
chronyd is actually ready to accept commands.
I reported a similar bug in postfix a few years ago: #959684.
Bug #772720 may also have been due to this kind of problem (although it's
hard to be certain).
