Do we actually have agreement on the anaconda/lorax side for the changes
required here?

What happens if the updated system (due to userspace, SELinux policy, what
have you) moves beyond something that can be properly rescued?

Will there be a fedup module to regenerate the rescue image on OS upgrade?
