And that is exactly what I want to happen.
This is not scary stuff - It can be determined without ambiguity.
The RFC amounts to this: Go from more specific to less specific.
PowerDNS CLEARLY does not do this.
That would make this a bug and make PowerDNS NOT RFC compliant.

Well - it is screaming for problems at least. Both CNAMEs, and wildcards are
complicated enough on their own.
If I read the RFC 1034 DNS algorithm (4.3.2), in this case the NS record
will win for whatever.test, but would lose for blah, which would then be a
CNAME for sd1.domain.com.
But who knows what might happen. This is scary stuff. Wildcards are fraught
with difficulties, as are CNAMEs.
