Greetings, All!

Couple of my scripts rely on ASH/DASH functionality that is not present in
BASH. (Namely "local -".)
To amend that, I make a symlink /bin/sh = /bin/dash .
But every time bash update, it overwrite the link.
So… How would I go about creating a handler that would restore the parity?
Will making a script /etc/postinstall be enough, or some additional magic is
necessary?
