In current model GNU Mach provides KEY codes to userspace programs,
and all modifying of keyboard layout must be done by Mach syscalls.

I think we should make some userspace program (1 process per keyboard,
if someone has more than one keyboard) that would map keyboard's
SCAN codes (received from Mach) to KEY codes (sent to terminal program).

currently :
          SCANCODES  (TRANSLATION)  KEYCODES
keyboard     ->          Mach          ->     terminal programs

proposed :
          SCANCODES        SCANCODES  (TRANSLATION)  KEYCODES
keyboard     ->      Mach     ->         keybd          ->     terminal programs
