upgrade-nixos: Скилл обновления NixOS до новой версии

--- name: upgrade-nixos description: | This skill upgrades NixOS to a new release version (e.g., 25.05 → 25.11). Triggers: "upgrade nixos", "upgrade to new release", "update nixos version", "move to nixos 25.11", "nixos release upgrade", "upgrade system version". Researches breaking changes, updates flake inputs, guides through upgrade. Not for flake.lock updates within same release (use upgrade-flake for that). --- # Upgrade NixOS Release Upgrade NixOS to a new stable release version. This involves updating version-pinned flake inputs and handling any breaking changes. ## Process 1. **Check current state** ```bash nixos-version nix --version ``` 2. **Identify version-pinned inputs in flake/flake.nix** that need updating: - `nixpkgs` (e.g., `nixos-25.05` → `nixos-25.11`) - `home-manager` (e.g., `release-25.05` → `release-25.11`) - `nix-darwin` (e.g., `nix-darwin-25.05` → `nix-darwin-25.11`) - `stylix` (e.g., `release-25.05` → `release-25.11`) 3. **Research the target release** - Use web search to find the latest stable NixOS release - Check release notes for breaking changes relevant to this config - Verify release branches exist for home-manager, stylix, nix-darwin 4. **Identify breaking changes** that affect this config: - Scan modules for services/packages that might be affected - Key areas: Hyprland, Docker, Steam, Secure Boot, impermanence 5. **Create upgrade plan** (use creating-plans skill): - Save to `thoughts/shared/issues/NN-nixos-<version>-upgrade/plan.md` - Include exact file changes with line numbers - Include verification commands - Include rollback instructions 6. **Execute upgrade** (when user is ready): ```bash # Edit flake/flake.nix with new versions just update # Update flake.lock just check # Build without applying (safe) just switch # Apply the upgrade ``` 7. **Post-upgrade verification**: ```bash nixos-version nix --version docker --version systemctl status docker tailscaled hyprctl version ``` ## What stays pinned (don't change) - `lanzaboote` - explicit version pin (e.g., v0.4.2), not tied to NixOS releases - `nixpkgs-unstable` - always tracks unstable - Inputs that `follow` nixpkgs - automatically updated ## Rollback Print out the instructions to: ```bash sudo nixos-rebuild switch --rollback git checkout flake/flake.nix flake/flake.lock ``` $ARGUMENTS
