One followup question to this: are there any limits to how the SOA
section is handled in this case? Can the SOA record be in the
$INCLUDE'd file, or does it have to be in the defined zone files
(which then would mean maintaining I guess two serial numbers)? I was
originally thinking that in that case, whenever changes are made to
the zonename.shared file, all that was really needed to be updated was
the "for-the-many" zone but I believe then the "for-the-few" machines
would begin to see an increasingly out of date version of the shared file.
