  Every couple years we go through this with ISC.  They come out with
a new version of BIND then claim that nothing other than Linux can
run it well.  I've seen this nonsense before and it's tiresome.

Incidentally, the query tool they used, queryperf, has been changed
to dnsperf.  Someone needs to look at that port - /usr/ports/dns/dnsperf -
as it has a build depend of bind9 - well bind 9.3.4 is part of 6.3-RELEASE
and I was rather irked when I ran the dnsperf port maker and the
maker stupidly began the process of downloading and building the
same version of BIND that I was already running on my server.

It's called "Anti-FreeBSD bias".  You won't find anything.

When you make remarks like that it's no wonder ISC is in the business
of slamming FreeBSD.  People used to make the same claims about djbdns
but I noticed over the last few years they don't seem to be doing
that anymore.

If nsd is so much better than yank bind out of the base FreeBSD and
replace it with nsd.  Of course that will make more work for me
when I regen our nameservers here since nsd will be the first thing
on the "rm" list.
