My apologies for this confusion. Barry was right, of course; I had
just read this incorrectly.
Every time you add A RECORD TO an existing zone, the master tells its
slaves [for sufficiently recent BIND versions].
Every time you add a zone, you must tell the slaves. That's because
there is no info about which servers are slaves for which zones. I
have zones [for various reasons] that are set up on hosts A, B, and C
as follows:
A B C
zone a master slave -
zone b master slave slave
zone c - master slave
zone d slave master -
There is no apriori way for the poor confused 'named' to know what I'm
going to do next. ;-]
