Yeah, we can definitely tidy that message up and make it more helpful.

But it's not exactly bogus; it's correctly reporting the errno it
encountered.  If you're not specific enough about your request, it tries
different filenames to figure out what you mean, and eventually gives up.
The "file not found" refers to "keyset-rootns-dnskey." if I recall
correctly.
