One of the things that got us is we didn't know BIND 8 automatically created
delegation records in a zone at the zone cut, if the nameserver knew of the
existence of the cut.
For example, if we have the following zones in our named.conf:
zone "example.com" { ... };
zone "sub.example.com" { ... };
and inside example.com, we do *not* have any delegation records for
"sub.example.com", BIND 8 will automatically create the NS records in
example.com.
BIND 9 will not do this. Be sure all of your zones that have zone cuts also
have the proper delegation records.
