Comment 89 for bug 1265192

Glad to see it's doing a better job detecting other OSes. I'd hesitate to call this bug "resolved" until the installer does a better job messaging to the user what it is about to do. For example, if it says it is going to "replace" one OS, it should also make it clear that this is actually an entire disk wipe. There are probably lots of partition types that ubiquity does not recognize.

Personally, I'd prefer to see this in a confirmation step that appears before any changes are made. It's pretty typical for Linux installers to have a summary screen saying, "here's what I'm about to do to your disk" and giving you a chance to catch issues before you lose all your data.
