That's good to hear. > This is such an obvious point Not at all. Nothing is obvious. For example, I can't see a good reason to remove the ability to create dedicated disks in the first place. What do we plan to do on architectures which don't support Microsoft partition tables? So why should it be obvious that support for such disks shouldn't be removed? Anyway, you're not describing the situation I was referring to. How are you going to change from dedicated to Microsoft compatible without rebuilding file systems? > that spreading FUD about it really calls into doubt your true > motives here. If there's any FUD here, it's coming from the suggestion that functional and useful features should be removed.
