I'm sorry to say, Chris, but you don't know what you're talking about. Saying that every distro has a proprietary installation scheme is way off. And YAST2 is far more than just an installation scheme. Without YAST SuSE is not SuSE. Try uninstalling it
Before you make a claim please check the facts. urpmi has a very nice GUI. It's a part of Mandrake control center. If you cared to check you would've found it under (who would have thought?!?) "Software management". And in the menu under Configuration/Packaging there's all you need: Install, Remove, Update, Sources Manager - all for urpmi). You did check there, right?
Once again, have fun with SuSE and their proprietary stuff, but don't spread lies and misinformation about the things you don't know.
