Except that the bash package now has the /bin/sh symlink in the package
and not as part of the postinst script. So if you change the link then
the next time you upgrade bash it will reset the /bin/sh link back to
bash.
But there is a solution to in the /usr/{share/}doc/bash/README.Debian
file for bash.
A kind of FAQ for bash on Debian/GNU\ {Linux,Hurd}
--------------------------------------------------
1. How can I make /bin/sh point to something else?
Type
dpkg-divert --add /bin/sh
and then point it to whatever you want. Upgrades to bash won't upgrade
the /bin/sh symlink. To put /bin/sh under dpkg control again, type
dpkg-divert --remove /bin/sh
