I am looking to move the private part of the KSK for my domains off my main nameserver. I've tried this with a test domain and get errors like this:
dns_dnssec_keylistfromrdataset: error reading /etc/bind/keys/example.com/Kexample.com.+999+99999.private: file not found
...
dns_dnssec_findzonekeys2: error reading /etc/bind/keys/example.com/Kexample.com.+999+99999.private: file not found
This guide recommends keeping the private KSKs offline without much further comment so I'm guessing it's ok to ignore these warnings? The zone continues to operate as expected and I can make changes fine (the errors just keep appearing).
If it is ok to ignore the warning, is there a way to disable it so the logs don't get filled up?
