--- Comment #7 from Ian Lepore <ian at FreeBSD.org> ---
This should no longer be a problem with our modern ntp.conf.  We've switched
from specific hostnames to the 'pool' feature that adds hosts from the pool as
needed.  The pool management is fully dynamic, periodically adding new servers
when there not enough available, which amounts to automatic retries following
dns failures at startup time.

When it is necessary to have ntpd set time before allowing rc processing to
conclude, options to ensure ntpd can resolve names include setting the
interface config to SYNCDHCP instead of plain DHCP, or add one or more
interface names to the netwait_if= list in rc.conf to ensure the names will
resolve at startup.
