The two instances would clash if both try to bind to port 53 on
addresses 127.0.0.1 and ::1. It's possible to configure the
full-featured name server not to bind to those addresses, and this is
indeed a good idea. However, I don't know of anything we can ship in
the default named.conf to make that happen without knowledge of the
IP addresses involved.
How about an rc.conf variable to control whether or not the resolver
instance of named gets killed when the full-featured instance starts?
Perhaps I can find a way to use a single multi-valued variable like
named=resolver # run mini named before ntpdate
named=full # run full named after ntpdate
named=resolver,full # run both
named=resolver,kill,full # run both, but kill resolver later
named=YES # same as named=full for compatibility
