Ok.  I've rewritten the patch.  Instead of loading the key on the owner
keyring at the same time as loading it on the system keyring, it waits
until all the keys are on the system keyring, before adding the
specified key to the owner keyring.  We loose the ability to specify all
the builtin keys, but at least for now, this isn't important.  For now,
we can identify a single builtin key, and when the UEFI patches are
upstreamed, we should be able to identify a UEFI key, as well.

thanks,

Mimi
