This is one of the things that bit Nadya at the AD plugfest. She
thought she'd debug bind using gdb, but didn't know that she needed to
do ". /etc/default/bind" before starting gdb. The resulting errors
were not helpful :-)

yep. Now multiply this by the number of Linux distros and versions of
distros out there :-)

I should make it clear again that I fully intend to keep going on our
bind9 support. Many larger sites are too tied to bind for us not to
support it I think. I'd just like a reliable, easy to configure
alternative that is testable in the build farm. I'm hoping Kai's work
might give us that!

Cheers, Tridge
