Many Linux installers suffered for years the situation that you would enter you password in the setup process with a different keymap than the one you got once the system then loaded, e.g. y-z were mismatched cause I was using QWERTZ instead of QWERTY. I think I saw something similar lately with on of the OSX'es.
