problem automating changes to a large number of zones.

No doubt others have built tools and environments around BIND 8,
and made their own bespoke migration headaches.

One of the big hold ups is the lack of backward compatibility,
vendors like SUN and HP can be slow to adopt these kind of
changes, and you have to wait till a major OS revision, and even
then some customers will expect the old configuration files to

Other than the security angle, it isn't a compelling upgrade,
and we all know how much computer security motivates people to
make changes, heck IIS market share improved during the month of
Code Red! No doubt some of those who found BIND 8 security
