My understanding is that refresh works on a zone-file basis, and that
slave servers must have an /etc/named.conf file that shows all the
domains being slaved, in the form:

(Above sample quoted from the book "DNS and Bind", O'Reilly, by Paul
Albitz & Cricket Liu, page 87.)

The key question is how do we AUTOMATICALLY get that into the file
without human intervention.

Once it's in the file, and the daemon is restarted, yes, the slave
nameserver will get the file at whatever interval is in refresh.

Every time I've seen this question asked, the answers always revolved
around using various ftp and other solutions to get the
"/etc/named.conf" from the master file, and then rename it.

However, to use an automated solution you'd need to presume you were
secondarying everything that appears on the primary server.  We don't
presume that; we ask our clients to tell us what they want slaved.
