I noticed that nsd (at least 3.0.6) when configured as secondary, no
longer stores the zonefiles in "plaintext". I assume all the data is
only stored in the nsd.db file.
However, the config for a zone still requires the zonefile: to be
present or else nsd fails with:
/etc/nsd/nsd.zones:10: error: previous zone has no zonefile
I personally would like to see nsd save the zone files in plaintext
even when used as a secondary. It makes it easier to verify things
for the DNS admin. But if that is not going to be implemented, then
it should not insist on a zonefile keyword in a seconday zone.

The diff file was specified via the nsdc patch command as "-x /var/lib/nsd/ixfr.db"
and is available there:
-rw-r--r-- 1 nsd nsd 607249 Nov 7 19:30 /var/lib/nsd/ixfr.db
But the pointer to the difffile seems to have gotten corrupted.
Is there anything else I can supply to assist debugging this?
Can you print the contents of the zone variable?
Also, if you could give me a (small) way to reproduce this, a config
file, nsd.db, ixfr.db file? (send it off list)
