Bind 9.20 inline signing - not signing whole file, only dynamic updated entries.

Hi Bind gang!

After upgrading to 9.20 I disabled default inline singing to get my
stuff working again.

Now I decided having a shot at inline signing but despite trying to
follow different guides I always get stuck at the same place.

I have an unsigned zone file, keys with correct permissions etc.

zone "example.com" {
        type master;
        file "example.com";
        allow-update {
                key update-key;
        };
        allow-transfer { secondaries; };
        dnssec-policy default;
        key-directory "/etc/bind/keys";
};

When I issue rndc reconfig after this, I see those lines in the log,
which to me, look good...

(unsigned): loaded serial 2007126012
(signed): serial 2007126013 (unsigned 2007126012)
(signed): sending notifies (serial 2007126013)

example.com.signed
example.com.signed.jnl

were created.

But when I check he zone on the secondaries, it's not signed. Same when
I get the zone by doing a AXFR from the primary - no RRSIG entries.

When I issue rndc signing -list example.com I get

No signing records found

according to the examples, I should get 'done signing'.

I tried: rndc sign example.com to force sign the zone. Nothing changes.

When I add an entry with nsupdate then that one entry is signed and the
SOA also is getting signed as the serial incremented.

What could I be missing?
