Bad advice. Unless the slaves see the master's serial number as "higher"
than their own, they'll never transfer the zone. One could wait for that
replication indefinitely.
Read RFC 1982 to see how serial number arithmetic really works. A
"reset" is possible, but setting the serial to 0 isn't always the way to
accomplish it.
