What strategy does chronyd use to resolve
the hostnames to IP addresses for its upstream time servers? I'm
guessing it does so once at startup and then caches the result for all
future use. Is that correct?
I had a number of systems I had to twiddle
with today because chronyd didn't seem to follow an IP address change we
made in DNS. I had specifically used a name via DNS to cope with
such a situation so was surprised by this behavior. To me it's the
first reason to use names ... an abstraction layer allowing redirections.
