Maybe your button should only allow "load this asdf system".
Then every code you use as a patch is a system that can be checked in
-- hopefully just the same as you'd have in a fresh image, though sometime
you need special magic (unintern, fmakunbound, etc.) to upgrade a live
system that you don't need in a dead one.

Grâce à la bureaucratie et au socialisme, il n'y aura bientôt que deux
partis en France: ceux qui vivent de l'impôt et ceux qui en meurent.

  left in France: those who live out of taxes, and those who die out of taxes.]
