Is anyone successfully running guix system on PBP

[ennoausberlin]

That's awesome. I'll give it a try!

I have managed to build a GUIX X11 environment on the Pinebook Pro. It took around 3 1/2 hours (kernel alone 2 hours), 
but afterwards I was able to boot into gdm/i3wm for now. I don't need a full XFCE or Gnome environment. emacs-native is working too.
I will experiment a little with stumpwm and exwm in the future. 

I can post my config here, if there is an interest

Yes, please do.

Ok. I am a little late, but it might be of use for you anyways.
