[dns-operations] FreeBSD and the slaving of the root zone

[Paul Vixie]

> How about "three primings from different sources"?

as long as there are three configured and three reachable, sure.  how
about some combination of "keep priming until you either run out of
configured servers or have found three who gave you the same answer,
and then if less than three answered or less than three were config'd,
all the ones you did get answers from have to match, and there has to
be more than one".

and yes, the original static hints should not be overwritten with
generated information.  though how and why and when to fall back is
something i don't know at the moment.
