It might help statistically (at least on some systems) but I'd prefer a
solution that prevents the race altogether. For now I've simply appended
"|| true" to the "chronyc onoffline" invocation. If chronyd updates the
connectivity at least once after it becomes ready to accept commands from
chronyc there should be no problem.

Not so easily. The problem is intermittent and the systems I've seen it
on so far are servers which I can't just reboot at will. Luis may have
(or have had?) a more suitable environment. I can try that change on
my test VMs to check for regressions, but the timings there are not
representative of physical servers.
