I've installed guixsd 0.10. Its probably a rooky problem but seem unable to solve it and I apologise! ;)
I'd like to change to keyboard layout from us to uk.

Ideally I'd like to set the keyboard layout in the config.scm file and 'guix system reconfigure'
Is this possible.?
I use DWM window manager and in my xsession file on other computer (running voidlinux) I've a line with "setxkbmap gb” which does the job. Which package does 'setxkbmap' belong to in guix, I can't seam to locate it. and if does not exist what other tools are there

Many thanks
Thierry
