The Mepis installer worked just as easily as it always has. There is no plymouth or splashy at the moment but there were no kernel errors and the Live DVD booted extremely fast anyway. The alpha is quick in virtualbox too! I installed all available updates with no breakage of any kind. I think that Warren and the Mepis community are going to have a very successful release on their hands.
Edit; Mepis was the first distro I ran full time, that is why I am so happy that Mepis 11 is looking so good.
