the query log file syntax is *dratcially* different.

some configuration file "features" are "gone", meaning that config
files will need to be tweaked and tweaked until the name server deigns
to start.

different classes (eg, inet, hesiod, chaos) need to be in different
"views", which forces people to learn what those are.

people need to learn to configure and to use rndc instead of plain old
ndc (not *completely* sure about this one, but i'm pretty sure that
the "unix" domain control socket goo is gone).

there are probably more.

don't get me wrong...i think i like bind9, but i know there are a
couple of things i'd really like from it that it just doesn't have.
it seems really close though...
