I have successfully install KDE 4.2.2 on two existing sidux systems, upgrading, using the smxi tool to the current system packages, removing select KDE 3.5 packages, and then upgrading to the latest KDE software, all under complete control of smxi. It all worked flawlessly, once more a great testimony of what sidux and smxi are capable of doing, providing the very latest in cutting edge software that works with reliability and great performance.
