>Description:

Due to network initialization taking longer at system startup on 8.0, ntpd cannot resolve hostnames when it is run by /etc/rc.d/ntpd


It spits out some messages that look something like:

ntpd_initres[1469]: host name not found: time.nist.gov
ntpd_initres[1469]: couldn't resolve `time.nist.gov', giving up on it
ntpd_initres[1469]: host name not found: time-b.nist.gov
ntpd_initres[1469]: couldn't resolve `time-b.nist.gov', giving up on it
ntpd_initres[1469]: host name not found: time-c.timefreq.bldrdoc.gov
ntpd_initres[1469]: couldn't resolve `time-c.timefreq.bldrdoc.gov', giving up on it


In this state ntpd isn't very useful until it is restarted after the network is ready to go.

>How-To-Repeat:

Configure time servers by hostname in /etc/ntp.conf, set ntpd_enable="YES" in rc.conf and reboot.
