Ah, now things are becoming clearer! You are using Plymouth for graphical boot animation and shutdown.

As far as I recall, to do what you want will require some actual C coding. You need to register a callback using ply_window_add_keyboard_input_handler() to get called whenever a user types something. Also note that Plymouth deliberating stops watching for keyboard input at certain times.

It is a while since I looked under the hood at the Plymouth source code but I do not think things have change much since then as I do not see much traffic on the Plymouth mailing list.
