9.2.3rc2 NS lookups failing

(reposting into a new thread)

I've built and installed 9.2.3rc2 to workaround the verisign issue.

Wildcards in the root are no longer a problem, however, I'm seeing what 
seems (IMVHO) to be incorrect behaviour.

The announcement of the new release states:

"...Briefly, a zone which has been declared "delegation-only" will be 
effectively limited to containing NS RRs for subdomains, but no actual 
data outside its apex (for example, its SOA RR and apex NS RRset)..."

By my reading of the above, I _should_ be able to do something like:

    dig ns $domain_that_exists.[com|net]

...and get an answer.  What I am instead seeing is:


root at severe# dig ns grape.com

; <<>> DiG 9.2.2rc1 <<>> ns grape.com
;; global options:  printcmd
;; Got answer:
;; ->>HEADER<<- opcode: QUERY, status: NXDOMAIN, id: 44941
;; flags: qr rd ra; QUERY: 1, ANSWER: 0, AUTHORITY: 0, ADDITIONAL: 0

;; QUESTION SECTION:
;grape.com.                     IN      NS

;; Query time: 252 msec
;; SERVER: 127.0.0.1#53(127.0.0.1)
;; WHEN: Wed Sep 17 20:48:12 2003
;; MSG SIZE  rcvd: 27


...and I see a corresponding "no!" in the logs:

Sep 17 20:48:12 severe named[5167]: enforced delegation-only for 'com' 
(grape.com


It seems that the only way to get around this new issue, and get the 
entire NS set for domain from the root, is to do a `dig any $domain` 
instead:

root at severe# dig any grape.com

; <<>> DiG 9.2.2rc1 <<>> any grape.com
;; global options:  printcmd
;; Got answer:

Is this the desired behaviour of `delegation-only`?  I'm very pleased 
that the new zonetype stops wildcards, but I'm somewhat concerned that 
something else may have been broken.

Thanks,

Dave
