Yes, I see a lot of "don't use" cname rr comments on the list. I think
that some of the reasoning behind those comments comes from the nature of
the cname rr and some people's desire to use / misuse them as a silver
bullet. I think quite a bit of the time many of the list memebers say
"use with caution" when it comes to cname rr's.
I do disagree with the "one place" aspect of your comments. cname rr's
are useful in RFC2317 and in the creation of generic zone database files;
which may be able to help you in your problem. I there have been a couple
of threads on this subject on the list in the last few days. Did I
suggest using a generic zone db file to you? If not, have you considered
if they might be helpful?

Yes, I believe older versions of BIND ignored the "cname and other data"
rule and allowed admins to create cname rr's at the zone apex. There was
a big to-do on the list when BIND 9 was getting popular and many people
were having problems migrating their zone database files that contained
cname rr's at the apex.

Yes, sorry, my previous comment was a little flip and meant to be funny.
Sorry about that... :)
