shells/bash port, add a knob which symlinks to /bin/bash ?

[Craig Rodrigues]

Hi,

I could live with this solution of additional port outside of the main
bash port, which creates the symlink and updates /etc/shells.

One other thing I am seeing is that many, many shell scripts are written
assuming "#!/bin/bash".
Forcing all upstream script writers to switch to "#!/usr/bin/env bash", or
to convert their scripts to "#!/bin/sh" and remove all bash-specific
behaviors, is getting harder and harder,
since many people are exposed to MacOS X and Linux on desktops.
