I neither against any of proposals.

But considering that we use those keys to verify other keys, they become
ca keys.
So from that point of view I think 'ca_keys' reflects functionality
quite ok.

localca_ prefix is may be not very relevant as builtin keys may
comesfrom kernel vendor (RH, Ubuntu)
and is not really local...

so let's decide on 'ca_keys'?

Thanks,
