No time for tests this weekend but finally onto it. Installed in VirtualBox. Got the same root account issues that PackRat already reported. I'm one of those geeks that like to use the root account and no xserver for the distro-upgrades (specially the big boys like xserver gcc, etc... when they come. though some times for small things I'm lazy to logout, du and go back to my regular user). Anyways. password is not recognized. Cannot use the root account. Otherwise it seems fine. Going to play a bit and check if anything else pops up.
Amazing installazion time, BTW. Oh, and no issues with my keyboard layout (won't miss the refracta installer, LOL). Will follow a spanish locale install in a while, just to check.
PS, used manual partitioning. Grub timeout is set at 2 sec in my case.
