Thinking about this some more - I think being able to do this at runtime is
actually important. If we add an additional xattr to the signatures then we
want to be able to update machine policy without forcing a reboot first,
otherwise we have a chicken and egg problem where we have to gate any new
package update against having a machine rebooted with an updated command
line (otherwise the signature validation will fail for packages that
contain new signatures)
