Building

Desktop (physical machine):

sudo nixos-rebuild switch --flake .#physshell

WSL:

sudo nixos-rebuild switch --flake .#wsl

Update package sources

nix flake lock

Tips

• nix run nixpkgs#nix-prefetch-git — get commit info (rev + hash) for fetchFromGitHub.
• Config can live outside /etc/nixos. Just run nixos-rebuild switch --flake .#[host] from the repo directory.
