I think nonguix also uses equivalent machinery for its Steam package: https://gitlab.com/nonguix/nonguix/-/blob/master/nongnu/packages/steam-client.scm#L392 https://gitlab.com/nonguix/nonguix/-/blob/master/nongnu/pack... Maybe there are docs on repurposing that as a general packaging escape hatch, which someone more familiar with nonguix could point to in a reply. Apparently there is an rpm-ostree-friendly RPM build of Nix that can be used to install Nix on Silverblue as well: https://github.com/nix-community/nix-installers/pull/8 https://github.com/nix-community/nix-installers/pull/8 It includes some code to get around the group/user management quirks that some other commenters have noted b0rked the Guix installer with Silverblue, so perhaps it gives an outline of how to install Guix on Silverblue for a hacker who'd like to try it :)
