Nix

Documentation for updateself 2.1.0. Versioned source.

Nix

Nix profiles and declarative systems are separate operations, on Linux or macOS.

updateself --only nix --dry-run
updateself --only nix --ask

Modern profiles use nix profile upgrade --all when available. Locked references remain pinned. Recognised legacy profiles use the selected user's configured channels and nix-env packages. Unsupported profiles are skipped.

Declarative activation

updateself --only nix --base-install --nix-config home-manager --ask
updateself --only nix --base-install --nix-config nixos --nix-flake "$HOME/config" --ask
updateself --only nix --base-install --nix-config darwin --nix-flake "$HOME/config" --ask

Select the kind applicable to your host. home-manager, nixos-rebuild or darwin-rebuild must already exist; system rebuild commands must be available to the privileged command environment. Home Manager runs as the selected user. --nix-flake is a local directory containing flake.nix.

Explicit input changes

updateself --only nix --base-install --nix-config home-manager \
  --nix-flake "$HOME/config" --nix-update-inputs --ask

The extra flag updates that configuration's flake.lock before activation. A random current directory is never implicitly selected. Failed/declined input updates prevent dependent activation. Review your configuration diff yourself.

No channel switching, daemon self-upgrade or automatic generation deletion is performed. --cleanup retains generations. This repository includes a pinned Nix package definition verified in CI; Nixpkgs submission/cache hosting is future work. See Packages and Releases.
