powerdns doesn't store signatures in the database backend when running
in live signing mode. (If you're running pre-signed you wouldn't store
the keys in the database in the first place.)

Presumably the database replication slaves duplicate the calculation of
RRSIGs and therefore need the (private) keys. I haven't tried
replication with 3.0 yet but I looked in my database and there are no
RRSIG (or DNSKEY etc) records.

Best regards,

I remember yesterday, but the memory is in my head now.
Was yesterday real? Or is it only the memory that is real?
