Yeah, that would be a problem, but I'd not expect this to happen
frequently with public NTP servers.

It would still print the names, chronyd works only with IP addresses
once the names are resolved and chronyc translates them back to names
(unless the -n option is used).

I'd not recommend that. Delaying start of chronyd until network is
probably a better idea.

You could also try cleaning /etc/resolv.conf before chronyd is
started, so it would keep trying resolving until the DHCP client
starts and rewrites the file.

The best option here would be update to a more recent version.
