Algorithm works as this:

1. Check if full keyboard configuration is already set

2. If no X layouts, check if they can be obtained from live system

3a. If still no configuration is present
|

|
-> use DEFAULT_KEYBOARD as console layout and fall through to...

3b. If only one of the keyboard layout or virtual console keymap is set
