The /bin/sh should really point to a reference shell that is accepted
for the release builds (like /bin/dash). It's is unfortunate that in
the distant past someone made a decision to simply soft link it to
bash.

I suppose it is impossible to make an etch+1 change to remove the
/bin/sh => /bin/bash coupling.
