include in /usr/share/X11/xkb/rules/evdev.xml (it does not really matter where but in <layoutList>)

        </variant>
      </variantList>
    </layout>
    <layout>

Now it should already be available to select in xfce etc.

usage in kernel ❡

To unlock the disk in kernel do

/etc/default/keyboard

# KEYBOARD CONFIGURATION FILE

# Consult the keyboard(5) manual page.

XKBMODEL="pc105"
XKBLAYOUT="decolemak"
XKBVARIANT=""
XKBOPTIONS=""

# see man, not important
BACKSPACE="guess"

Then include that in initramfs

/etc/initramfs-tools/initramfs.conf

.
.
.
KEYMAP=y
.
.
.

grub ❡

To use this map in grub too (for CBFS)

grub-kbdcomp -o decolemak.gkb decolemak

You can ignore errors but make sure its not an empty output file and the symbols were found

copy the gkb to /boot/grub or on cbfs

grub.cfg needs to have

insmod at_keyboard
insmod usb_keyboard

if [ -f (cbfsdisk)/keymap.gkb ]; then
    keymap (cbfsdisk)/keymap.gkb
fi

or similar like keymap /boot/grub/keymap.gkb

There is a lot that can go wrong here, see
