Hello Ricardo,
doesn't guix system not use eudev, in base.scm I see under
udev-configuration under package udev-configuration-udev (default eudev)
I think that file is very specific and if you have custom rule files why
not custom hwdb files. The problem is that this more a flavor, I use a
japanese keyboard layout and use the many thumbkeys in a "ergonomic"
way. So space as enter and the enter button as end, that is not what
everybody would want with such hardware.
So again in short, yes I think if you can add custom rule files I think
you should also be able to add custom hwdb files.
