Comment 82 for bug 61463

#!/bin/bash isn't really an alternative. Bash isn't guaranteed to be installed in /bin with that name on all systems.

I agree that any script which uses /bin/sh and relies on any features not present in sysV bourne shell is broken by definition. However, changing this symlink on a global level was a very poor choice in my opinion.

People who want these script problems fixed are the ones who should be running with the non-standard link, not the majority of us. If those folks beat the bushes, expose the problems, and get them fixed, then the link could be changed at some point in the future. As is, things just fail mysteriously.
