Indeed.  There is one type whose name begins with a '.' that's sort of
internal to the kernel (".request_key_auth") that I definitely don't want
userspace to try creating.

The question of whether the description of a non-keyring key is permitted to
begin with a '.' is a separate issue to this patch.  We'd have to be sure that
no one is using keys of such a form.
