May be already fixed, I used the beta installer, but I'd like to discuss it if it still isn't fixed.
I chose the keyboard layout "german/austria" in the installer. In X11 it got set, but the console layout is still wrong (english in my case).
I'm from Austria, so I set my layout to the austrian one instead of the german one (which actually is the same :D). This caused that the keyboard layout in vconsole.conf is "at" instead of "de". May be a upstream bug of calamaris though.
~$ cat /etc/vconsole.conf KEYMAP=at
There just is no at keymap, it's actually the de one.
