flake: fix lib.trivial.version when used from a flake
A lot of fetchers from Nix's own `libfetchers` also provide the
information that `lib.trivial` aims to expose with
`version`/`versionSuffix`/`revision`. In fact you don't even need a
`nixpkgs` channel to get a proper version suffix because of that!

Unfortunately this isn't used currently. When using the
nixpkgs flake, but not `nixpkgs.lib.nixosSystem` to build a NixOS
configuration, the version will always be `YY.MMpre-git`. One example is
e.g. `colmena` which evaluates configurations via
`import (npkgs.path + "/nixos/lib/eval-config.nix")`.

This patch ensures that the version suffix (i.e. the normalized last
modified date + git revision) is correctly exposed in `lib.trivial`.
Additionally, the change is injected into the following locations:

* `lib`: with that, something like

      $ nix eval nixpkgs#lib.trivial.version
      23.05.20230921.cf8bf79

  is working fine (i.e. rather than `23.05pre-git`).

* `legacyPackages` to make sure that e.g. `legacyPackages.<system>.nixos`
  has correct version info. This also applies to everything else using
  `pkgs.lib.trivial` for that purpose.

* `overlays.default` which can be applied to a `nixpkgs` and changes the
  previous `pkgs.lib` from said `nixpkgs` to also contain the correct
  `version`/`revision`/etc..

  This is useful for people using `nixpkgs` as flake input, but
  importing it manually with

      import inputs.nixpkgs { }

Nixpkgs is a collection of over 80,000 software packages that can be installed with the Nix package manager. It also implements NixOS, a purely-functional Linux distribution.

Manuals

  • NixOS Manual - how to install, configure, and maintain a purely-functional Linux distribution
  • Nixpkgs Manual - contributing to Nixpkgs and using programming-language-specific Nix expressions
  • Nix Package Manager Manual - how to write Nix expressions (programs), and how to use Nix command line tools

Community

Other Project Repositories

The sources of all official Nix-related projects are in the NixOS organization on GitHub. Here are some of the main ones:

  • Nix - the purely functional package manager
  • NixOps - the tool to remotely deploy NixOS machines
  • nixos-hardware - NixOS profiles to optimize settings for different hardware
  • Nix RFCs - the formal process for making substantial changes to the community
  • NixOS homepage - the NixOS.org website
  • hydra - our continuous integration system
  • NixOS Artwork - NixOS artwork

Continuous Integration and Distribution

Nixpkgs and NixOS are built and tested by our continuous integration system, Hydra.

Artifacts successfully built with Hydra are published to cache at https://cache.nixos.org/. When successful build and test criteria are met, the Nixpkgs expressions are distributed via Nix channels.

Contributing

Nixpkgs is among the most active projects on GitHub. While thousands of open issues and pull requests might seem a lot at first, it helps consider it in the context of the scope of the project. Nixpkgs describes how to build tens of thousands of pieces of software and implements a Linux distribution. The GitHub Insights page gives a sense of the project activity.

Community contributions are always welcome through GitHub Issues and Pull Requests.

For more information about contributing to the project, please visit the contributing page.

Donations

The infrastructure for NixOS and related projects is maintained by a nonprofit organization, the NixOS Foundation. To ensure the continuity and expansion of the NixOS infrastructure, we are looking for donations to our organization.

You can donate to the NixOS foundation through SEPA bank transfers or by using Open Collective:
