bind replication

[Jack Tavares]

A further complication on this is if you are using dynamic updates.

If you are using dynamic zones, bind will create journal files.

If you were to copy over the zone files and journal files and do
a reload, bind determines whether or not to reload the zone based
on the timestamp of the zone file. It does not look at the time on the journal file.

If you wished to sync zone files in this manner, with dynamic zones, you would need
to freeze the zones on the sending side, which forces a write of the data that is in the journal file to the zone file,

freeze the zones on the receiving side
then copy the files over
reload
unfreeze zones on both sides.
