I've been plagued with this for years (well, a couple anyways) on several
of my servers. As I never saw anyone else mention it. I assumed it was just
"me". ;-)
rc(8) has a mountlate. Seems to me there ought to be a "startlate" key as
well. While this won't fix the cause introduced. It might at least solve
the problem.
create an /etc/rc.conf.local and move your host/nic related things into
it followed by your "named" entry. Leaving everything else in /etc/rc.conf
This (should) source all the rc.conf.local entries ahead of the rc.conf
entries. Thereby providing name resolution before ntpdate(8)/time sync
service(s)
