Both of these are a really bad idea.  If anything goes wrong at the
wrong moment, /bin/sh would be left nonexistent and the system would
be totally hosed.

The _only_ safe way to manage /bin/sh is by rename(2)'ing something
over the top of it, like dpkg does.  Neither update-alternatives nor
diversions should be applied to the essential files in Essential
packages.
