Hello,
The installer gained support for keyboard layout switching from every
step recently[1].
It is also possible with commit 2729cb406d9f3e9eb22cc660f887138134edb3a8
to specify comma-separated keyboard layouts, this way:
--8<---------------cut here---------------start------------->8---
(keyboard-layout "ar,us" #:options '("grp:alt_shift_toggle"))
--8<---------------cut here---------------end--------------->8---
Now it would be nice to support multiple keyboard layout selection from
the installer, so that a configuration like to one above is generated.
Thanks,
Mathieu
