Blah blah blah. I'm actually pretty tired of this argument. I realize that
bind 8 has some ugly spots, but it's still the bugs we know, vs. the bugs
we don't know in bind 9. I'm also a little suspicious of all the people who
claim that there is this or that present in the bind 8 source, but haven't
actually submitted any fixes.

Ummm... how do you make the leap of logic that says that new features
added to a new code base are better or more stable than new features added
to an established code base? My point earlier was that both code bases have
their own unique problems.

Once again, I have nothing but respect for the people at nominum, and the
herculean task that faces them. However, as I pointed out previously the
migration path still has too many hurdles (and unseen pitfalls) for most
people, IMO. I would feel a lot better about it if someone at nominum was
willing to be a little more flexible in terms of listening to the concerns
already voiced in this area, but c'est la vie. Also, the mere fact that
most of the code in bind 9 is produced "by contract," doesn't really enter
into this discussion. I am a proffesional programmer and I know the
problems associated with this kind of project. Thus my concerns.

On this point I agree with you. However I don't see any point in
encouraging people to upgrade exclusively for the purpose of getting them
to use bind 9. Since this entire e-mail basically restated points made
previously, I think I'll leave it at that.
Perhaps the greatest damage the American system of education has done
to its children is to teach them that their opinions are relevant
simply because they are their opinions.
Do YOU Yahoo!?
