Hi Danny. With great excitement I edited my config.scm to include kmod,
ran guix system reconfigure, and rebooted my machine. Unfortunately my
changes did not seem to fix the issue. I hope the session below can help
us further. Thanks so much for working on this issue.
allana@guixsd ~$ docker ps
Cannot connect to the Docker daemon at unix:///var/run/docker.sock. Is the
docker daemon running?
