+If this is @code{#f}, the bootloader's menu (if any) uses the default keyboard
+layout, usually US@tie{}English (``qwerty'').

+Otherwise, this must be a @code{keyboard-layout} object. For instance, the

+@example
+(keyboard-layout "fr" "bepo")

+The layout name and variant must match an existing layout in the

+This option is currently ignored by bootloaders other than @code{grub} and
