I was trying to run some GUI software in a guix container, and would like to have GPU access in it.  However, I later found out that if I gave network access to the container, it seems like unable to properly find the GPU.  The following are the commands that I run and the output I got:

The only difference between these two executions are the `-N' flag.  I also had a look at the related guile code, and it seems like the `-N' flag is only doing two things:
  1. bind several network related files to /etc
  2. share network namespace to the container

I've had a few other guix users tested the commands, and they reported the similar results.

Some info about my environment:
kernel version: 6.0.7
mesa   version: 21.3.8
