Hi Ludo, I've tried 'guix run' for a little bit and I think it has a lot of potential! One of the problems with guix environment containers is that it can take quite a while to build. 'guix run' could solve that.
Adding Xpra to 'guix run' and/or 'guix environment' in some way could definitely be handy for isolation purposes. For the most part it would just consist of starting up a Xpra socket and exposing that to the container, then maybe automatically attaching to it. I've pushed a change to Xpra to start Xvfb with '-nolisten local'. This disables abstract sockets for the Xorg server that gets started with Xpra. As a result, using the commands below, you should be isolated even on the same network namespace. I can also write something for the Guix documentation, though i'm not sure if that's considered out-of-scope.
