FreeBSD router10 10.0-BETA3 FreeBSD 10.0-BETA3 #0 r258162: Fri Nov 15 10:48:21 UTC 2013     krad at router10:/usr/obj/usr/src/sys/me  amd64
>Description:
bind has the following config options to stop the rc startup scripts running until the name server is up and running

named_wait="yes"                 # Wait for working name service before exiting
named_wait_host="localhost"     # Hostname to check if named_wait is enabled

The rc script for unbound doesnt have such a feature, therefore on machines where the resolver is localhost, things like ntpd which depend on name resolution can break.

[root at router10 /usr/src]# rcorder /etc/rc.d/*| egrep -n "(unbound|ntp)"
50:/etc/rc.d/local_unbound
74:/etc/rc.d/ntpdate
127:/etc/rc.d/ntpd

Adding similar delay functionality would be usful

>How-To-Repeat:
boot a machine with unbound as the name server and localhost specified and the resolver and have a resolution dependent service such as ntpd running
>Fix:
replicating the named_poststart () would be sufficient
