if we could structure the signature key hierarchy correctly (in a way
which permits revocation of the signatures of buggy/insecure modules), I
suspect we could in fact use module signatures to prevent incompatible
modules from loading.

But with both Live Upgrade and ZFS root there's no pressing need to do
in-place updates -- update a copy/clone of the root instead.
