So, having removed the immutable attribute from / and run the guix-install.sh script, the first issue I have is that the script thinks the group 'kvm' exists, because 'getent group kvm' returns successfully. However, if you try to create a user and add them to the kvm group, you get an error about the group not existing. Looking at the contents of /etc/group, there are only 5 groups and none of them are 'kvm'. At the very least it seems that the Guix install script is making some assumptions about the system that Silverblue breaks, which does make me wonder a bit about using the two side by side. Additionally, I have found some posts as far back as 2017 regarding using Guix or Nix on Fedora Atomic Linux or Fedora Container Linux (it seems the Silverblue name is more recent) and the fact that we're still puzzling it out 5 years later without much in the way of documented success does make me question the viability of the idea a bit.
