Comment 2 for bug 1308778

We should definitely be printing out a list of files that would need to be removed so that they can be replaced. I'm not sure I like the idea of having the script doing the deleting. It seems like it would be easy to make mistakes and we are not a configuration management tool.

It's also important to note that we'll be discouraging the use of pkg_setup in a future commit. https://review.openstack.org/#/c/80819/
