I have a problem with ntpd on many of our servers running

Ntpd can't resolve host names on boot. This error did not existed on 7.x

I know there is rc.d/netwait in 8-STABLE, but it is not available on
8.2-RELEASE and I think that there is some regression as this error
was not there in the time of FreeBSD 7.x.
The problem is that the networking layer is not TRULY available by the
time ntpd starts. This does have to do with NIC drivers, but the same
behaviour can be seen on all NICs, including excellent ones like em(4).
You can use the rc.conf netwait_* variables to solve this problem. I'm
the author of the script that got committed so that's how I know. :-)
An example:
netwait_enable="yes"
netwait_ip="4.2.2.1 4.2.2.2"
netwait_if="em0"
If you need help setting this up, let me know.
Yes, I know you are the author and I tested one of the earlier version
floating around a mailing list, and I already have it on some 8-STABLE
machines where it is included in base /etc/rc.d - thank you for your work!
My main concern is that I never needed it on previous FreeBSD versions.
I am using ntpdate / ntpd from FreeBSD 4.x days and it always worked
fine. So there is some "bad change" on FreeBSD 8.x.
