Hi,different versions of images should be done only once the package management works and is in place, I think. Because then you know you can morph any version of Haiku into any other or a mix of both via a controlled mechanism. Right now, you couldn't be sure that an incompatibility in your system isn't caused by installing more stuff on top. I'd rather have only one distribution of Alpha 3 for now.
