At the moment, I've taken the plunge for Mageia 3 64-bit, mounted all my partitions over here, including my /home. As I set up my Mageia user with same name, password, and uid, it just works to use my old files (knock on wood).
So, far, except I have to find gtkam, somewhere, it is a pretty smooth transition, just like Rosa 2012.1r1 but printing works.


do switch back!
