Ack. I want to put forward that we should get the postinstall scripts moved from bash to dash as a first step even then. > I'm still toying with the idea of doing a test release of both bash and > dash that flips /bin/sh between them; but I'm still stuck on the problem > that a user MUST upgrade (or downgrade) both packages in tandem, or else > risk being left without a /bin/sh at all.

I'd test that in production. I don't really need handholding w.r.t. update and potential downgrade process, so if you'd put the two packages somewhere into an unofficial repo that would work for me.
