This is supposing /bin/sh can only be "ash" or "bash". There may be
another /bin/sh implementation (e.g., zsh) that does support the --version

Actually, setup will unlink /bin/bash and then install a new /bin/bash
over it. Thus, /bin/sh won't be upgraded even on filesystems that support
hard links. So *it* is a showstopper of sorts...
I'd suggest doing a binary compare on /bin/sh and /bin/bash in a preremove
script, and deleting /bin/sh if they are the same (as is done with config
files). This will work on both Win9x and NT-based systems.

FWIW, there was talk about a "configure-shell" script that sets the shell
at the user's request. Given the recent discussion of the alternatives
package (and Buzz's executable wrappers instead of symlinks) this sounds
like an interesting thing to try.
