But internal root name servers, which are what Christine is
describing, only know about a small number of apex zones.
If you ask an internal root name server about a zone whose
ancestor doesn't appear in the root zone, you get NXDOMAIN.

No, she's not.  In 2, she's describing an internal root setup,
and a correctly configured internal root name server will
not log that error message.  It *is* a root name server, so
why should it?

Forward only worked in previous versions of BIND, too (BIND 4,
for example).  Even though it would produce an error message,
the name server would work correctly.
