Anaconda: Setup custom keyboard layout for LUKS unlock (LUKS unlock screen always uses en-US keyboard layout)

Workaround / post-install fix

Option 1

Set the keymap on the kernel command line (see https://www.freedesktop.org/software/systemd/man/latest/vconsole.conf.html), using rpm-ostree kargs --editor for example:

... vconsole.keymap=fr

Option 2

Run:

rpm-ostree initramfs-etc --track=/etc/vconsole.conf

and reboot.

For the second option, you do not have to manually specify the keymap to use but this will make updates apply slightly slower.
