Yes, but more specifically what is altering the zone files and
how?

You say "you aren't making the changes on the master server",
but I wasn't really interested in the actual person, but the
procedure.

Presumably after the files are modified, it is reloaded using
rndc reload, or someother procedure. Why can't that procedure be
altered to call rsync?

Thus the only exception to this kind of procedure I've seen is
for DDNS, for which IXFR is probably more appropriate for the
reasons given.
