Comment 3 for bug 613510

This is debatable. One of the issues with trying to do smarter detection here is that, practically by definition, if you're using rescue mode then something is broken and you're trying to recover from it. I don't want to try to second-guess too much the set of things that might be wrong with your filesystem, and some of those things might involve it being detected incorrectly.

It might be worth at least showing the detected filesystem type.
