I have not built bind with Dampening yet, I just got the RRL patch
going last night. Will try to deploy an instance of the dampening
patch perhaps tonight.

I am up to my neck in open (and closed) source projects, but if nobody
else will step up to the plate to maintain a Debian style PPA for bind
with Dampening, I could perhaps (reluctantly) take care of getting
that off the ground....<sigh>....it will be for my own good anyway
come time to do an O/S update.....okay.....I'll do an Debian/Ubuntu PPA...

Does the RRL patch need such a PPA as well?
