Adding zones to PowerDNS with 'notified_serial' set breaks native DNS replication
short description
When creating a new zone, the powerdns-plugin inserts the domain with the field "notified_serial" set to the inital serial from SOA. Therefore the pdns server does not notify any slaves since notified_serial == current serial from soa. This breaks zone replication to e.g. bind slaves.
correct behaviour
Leave out "notified_serial" when adding a new zone or set it explicitly to NULL.
environment
Any.
