Yes, the destination keyring can be 0. If you don't specify a destination
keyring, then:
(1) If the key is found to already exist, the serial number is returned, but
no extra link is made.
(2) If an error occurs other than "this key doesn't exist", then you'll just
get the error.
(3) If we have to construct a new key, this will be attached to the default
keyring (as there's no destination keyring to attach to).

There's a /etc/request-keys.d/ directory now.
