AW: Simplistic serial number roll back

[Klaus Darilion]

Yes it does. I guess all name servers offer a command to force a transfer of the zone without checking the serial. The ones I use support that:

Bind: rndc retransfer <zone>
NSD: nsd-control force_transfer <zone>
PowerDNS: pdns_control retrieve <zone>
Knot: knotc zone-retransfer <zone>
