Hi Sebastian,

Thanks for the report. As Rickard mailed before, some issues have been
fixed in trunk.

> - changed TTLs for a record, without proper signature update

This now also has been fixed. There could still be some weird behavior
if the TTLs for RRs in the same RRset differ. However, this situation is
deprecated according to RFC 2181.

If OpenDNSSEC encounters such RRset with varying TTLs, it sets all TTLs
to the value of the lowest TTL (also according to RFC 2181). Because it
then changes the TTL value, next time when reading the zone, it will
treat it as if the RR was updated, even if no change has been made to
the unsigned zone (because OpenDNSSEC changed the TTL and the TTLs now
differ).

Best regards,

Matthijs
