Description of problem: I have a computer with luks encryption. After preupgrade downloaded all packages, I rebooted and then anaconda asked me for hard disk password. I entered it but the computer did not reconnize it. Asking on IRC, a person told me that my problem was about different keyboard layout. So we need a keyboard layout choice menu in anaconda upgrade process.
This is obsolete as of Fedora 18, now we're using fedup for upgrades. fedup may have its own issues with keyboard layouts - we're looking into that - but they should be filed separately if so.
