How to update zone with dnssec-policy

[Matthias Fechner]

Dear all,

I have the following problem that changes in a zone file do not get 
active, no matter if I reload the zone using rndc or restarting bind 
9.16.42 on FreeBSD.
If I update a zone I edit the zone file, adapt the serial in the SOA and 
normally do a rndc reload fechner.net.

The nameserver is more or less setup like it is described here:
https://wiki.idefix.fechner.net/freebsd/bind/

The zonefile for domain fechner.net are in directory: 
/usr/local/etc/namedb/master/fechner.net

It is not a dynamic zone file or better I cannot freeze it:
  rndc freeze fechner.net
rndc: 'freeze' failed: not dynamic

But if I delete the files:
fechner.net.jbk
fechner.net.signed.jnl

and restart bind, zone changes are correctly loaded and I can see an 
increased serial in:
dig -t soa fechner.net.

Would be nice if someone can explain me, how I need to edit a zone file, 
that has a dnssec-policy attached that modification get active, without 
the need to delete the `*.[jbk|jnl] files.

Thanks a lot.

Gruß
Matthias
