Comment 4 for bug 349336

I'm not sure the "Are you sure you want to remove these packages?" will help either, but then again, I would call the entire janitor a papercut. A user seeing that message will probably be afraid too and close the janitor. That is a lot more likely than the user starting to googling every package to check if it's safe to remove. I have said so before, and say it again; the computer janitor should not even offer to remove packages the user needs! How do we know what the user needs? He probably wants to keep the manually installed packages at least..?
