A slave server writes a copy of the zone to a file, not a copy if the
zone file that the master file has. That copy has an identical set of
data for the zone as the master server has. It doesn't have to be
written in exactly the same way. For instance, all the resource
records could have explicit TTLs instead of a $TTL directive at the
top of the file. Or maybe the records in the slave zone file inherit
an explicit TTL from the first record in the file.
