Hi Rodrigo,

  A thoroughly Guix way to do this would probably be to just set the
  `keyboard-layout` property in your operating system record like so:

```system.scm
(operating-system
 ...
 (keyboard-layout (keyboard-layout "emacs"))
 ...)
```

This should update the keymap at your tty sessions, but I'm not sure if
it will propagate into your X session. Perhaps someone else here has
tried it?

I also run EXWM as my window manager on Guix System, and I've addressed
this keymapping issue by just inserting it into my $HOME/.xsession file
like so:

```.xsession
# Change cursor to left arrow
xsetroot -cursor_name left_ptr

# Set keyboard repeat rate
xset r rate 200 60

# Change Caps Lock to Ctrl
setxkbmap -option "ctrl:nocaps"
setxkbmap -option "terminate:ctrl_alt_bksp"

# Start Emacs with the exwm script:
exwm
```

Have fun and happy hacking!
  Gary
