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

I actually like the idea of every interative resolver having
a copy of the root zone. I've said this for many years to
Paul. It addresses a whole classes of problems which really
cannot be addressed any other way.
At times I've proposed that every ISP copy from the roots
and every end user site/organizati copy from their ISP.
Internally a site/organization would designate one or two
server from which the others would transfer the zone. This
would spread the load.
If you care about information leaks via the DNS you really
do want your own copy of the root zone.
If you want your site to run well when the external link
is down you want your own copy of the root zone. It's the
major typo catcher.
The real question is how to do the distribution, not whether
it is a good idea or not.
