NixOS

NixOS is a Linux distribution based on the purely functional package management system Nix. More information can be found at https://nixos.org/nixos and in the manual in doc/manual.

Testing changes

You can add new module to your NixOS configuration file (usually its /etc/nixos/configuration.nix). And do sudo nixos-rebuild test -I nixpkgs=<path to your local nixpkgs folder> --fast.

Commit conventions

  • Make sure you read about the commit conventions common to Nixpkgs as a whole.

  • Format the commit messages in the following way:

    nixos/(module): (init module | add setting | refactor | etc)
    
    (Motivation for change. Link to release notes. Additional information.)
    

    Examples:

    • nixos/hydra: add bazBaz option

      Dual baz behavior is needed to do foo.

    • nixos/nginx: refactor config generation

      The old config generation system used impure shell scripts and could break in specific circumstances (see #1234).

Reviewing contributions

When changing the bootloader installation process, extra care must be taken. Grub installations cannot be rolled back, hence changes may break peoples installations forever. For any non-trivial change to the bootloader please file a PR asking for review, especially from @edolstra.

Module updates

Module updates are submissions changing modules in some ways. These often contains changes to the options or introduce new options.

Reviewing process:

  • Ensure that the module maintainers are notified.
    • CODEOWNERS will make GitHub notify users based on the submitted changes, but it can happen that it misses some of the package maintainers.
  • Ensure that the module tests, if any, are succeeding.
    • You may invoke OfBorg with @ofborg test <module> to build nixosTests.<module>
  • Ensure that the introduced options are correct.
    • Type should be appropriate (string related types differs in their merging capabilities, loaOf and string types are deprecated).
    • Description, default and example should be provided.
  • Ensure that option changes are backward compatible.
    • mkRenamedOptionModuleWith provides a way to make renamed option backward compatible.
    • Use lib.versionAtLeast config.system.stateVersion "23.11" on backward incompatible changes which may corrupt, change or update the state stored on existing setups.
  • Ensure that removed options are declared with mkRemovedOptionModule.
  • Ensure that changes that are not backward compatible are mentioned in release notes.
  • Ensure that documentations affected by the change is updated.

Sample template for a module update review is provided below.

##### Reviewed points

- [ ] changes are backward compatible
- [ ] removed options are declared with `mkRemovedOptionModule`
- [ ] changes that are not backward compatible are documented in release notes
- [ ] module tests succeed on ARCHITECTURE
- [ ] options types are appropriate
- [ ] options description is set
- [ ] options example is provided
- [ ] documentation affected by the changes is updated

New modules

New modules submissions introduce a new module to NixOS.

Reviewing process:

  • Ensure that all file paths fit the guidelines.
  • Ensure that the module tests, if any, are succeeding.
  • Ensure that the introduced options are correct.
    • Type should be appropriate (string related types differs in their merging capabilities, loaOf and string types are deprecated).
    • Description, default and example should be provided.
  • Ensure that module meta field is present
    • Maintainers should be declared in meta.maintainers.
    • Module documentation should be declared with meta.doc.
  • Ensure that the module respect other modules functionality.
    • For example, enabling a module should not open firewall ports by default.

Sample template for a new module review is provided below.
