Here's what I have been able to do for this week.
td;dr
I believe I have identified conceptually how to do some of these things.
This project breaks down into four areas
Getting the layout to work with:
1) grub
2) linux's initrd
3) console
4) X/wayland's layout
5) How to do the above
1) I was not able to get grub to generate an alternate keyboard layout.
#+BEGIN_SRC sh :results output :exports both
sudo grub-kbdcomp -o /boot/grub/dvorak.gkb dvorak
#+END_SRC
#+RESULTS:
: /home/joshua/.guix-profile/bin/grub-kbdcomp: line 76: ckbcomp: command not
found
: ERROR: no valid keyboard layout found. Check the input.
Do we have ckbcomp installed? How do I install that?
2) Linux's initrd
The manual mentions that there are three ways to customize your initrd.
Hopefully I'll be able to use the highlevel base-initrd procedure.
Furthermore, if you need lower-level customization, the ‘initrd’
field of an ‘operating-system’ declaration allows you to specify which
initrd you would like to use. The ‘(gnu system linux-initrd)’ module
provides three ways to build an initrd: the high-level ‘base-initrd’
procedure and the low-level ‘raw-initrd’ and ‘expression->initrd’
procedures.
3) console
This shouldn't be all that hard to do. We just have to add a
console-keymap-service.
4) X/Wayland's layout shouldn't be all that hard to do too. X is just
a simple xorg-start-command tweak. I'm not certain how to do the same
for wayland yet.
5) Now, how do I go about doing the above? I thought about modifying
%base-services and %desktop services, but some users won't use those
variables. So I am going to have to do some change at a deeper level.
I believe that I found the reconfigure module in the guix source code,
and I see the variable called "operating-system-user-services". My
intent is to modify this variable, and that should be how a good-old
reconfigure will change your layout.
Thanks,
