Some secondaries are configured only to allow AXFRs from a specific
address, which Murphy says will be not the default. I think that while
it is creeping featurism, its something that has to be done.
'src: 127.0.0.1', in the zone definition sounds not terribly dumb. :)
If there is a possibility of several things going wrong, the one that
will cause the most damage will be the one to go wrong.
