Sorry!  It is entirely my fault.  I had not known that if I don’t put
a keyboard-layout field in set-xorg-configuration, I always get
U.S. layout.

I agree that staying close to XKB is a good reason.

Thank you for all your work!!

I can only use the usb_keyboard input terminal and cannot use
at_keyboard with my Macbook.  Not specifying a terminal_input was the
right resolution for that bug, because now it uses usb_keyboard
automatically.

It’s just that usb_keyboard cannot use keyboard layouts, it seems, and
overall GRUB does not support all features needed from keyboard
layouts according to the manual.  Not encrypting grub’s file system
seems easier.
