I tried un-excluding it: nothing.

[but querying it for NS gives SERVFAIL]

> Midnight insight: glue records???  The two listed NS are below the

I think I'm onto something; with the above stub zone for
"concordia.ca" (which transfers information listing two NS
records as ns1.concordia.ca and ns2.concordia.ca but no glue
records), I get SERVFAIL (after a clean start of "named").

And in that circumstance, the other two stub zones I have set up
(for the IPv4 and IPv6 reverse zones for my parent networks) also
transfer the same set of two NS records, and also fail.

If I comment out the stub zone for "concordia.ca", but leave
in the two "reverse IP" stub zones, then these two zones work
correctly: when I query for NS, they give me ns1.concordia.ca
and ns2.concordia.ca, with their A records in the additional
section.

I think that clinches it: the implementation of stub zones
indeed "replicates only the NS records", but not the needed
glue records, so it cannot work in cases where all of the
listed NS are within the zone itself.

It would be a nice enhancement to make the stub zone pick up
glue records.  Is this something I should report separately?


Meanwhile, I'll try a static-stub zone for this case...


Tony Finch has also suggested:

> Try rndc trace 10. The debug logs are written to named.run (not
> syslog) by default.

After a bit of tweaking of my logging configuration, I was
able to get the trace output.  I append it (for a query on
the NS records of concordia.ca, with the stub zone in effect),
in case it is of use to anyone.
