wpa_supplicant: allow both imperative and declarative networks
For a while now it's possible to specify an additional config file in
`wpa_supplicant`[1]. In contrast to the file specified via `-c` this was
supposed to be used for immutable settings and not e.g. additional
networks.

However I'm a little bit unhappy about the fact that one has to choose
between a fully imperative setup and a fully declarative one where the
one would have to write credentials for e.g. WPA2-enterprise networks
into the store.

The primary problem with the current state of `wpa_supplicant` is that
if the `SAVE_CONFIG` command is invoked (e.g. via `wpa_cli`), all known
networks will be written to `/etc/wpa_supplicant.conf` and thus all
declarative networks would get out of sync with the declarative
settings.

To work around this, I had to change the following things:

* The `networking.wireless`-module now uses `-I` for declarative config,
  so the user-controlled mode can be used along with the
  `networks`-option.

* I added an `ro`-field to the `ssid`-struct in the
  `wpa_supplicant`-sources. This will be set to `1` for each network
  specified in the config passed via `-I`.

  Whenever config is written to the disk, those networks will be
  skipped, so changes to declarative networks are only temporary.

Nixpkgs is a collection of over 60,000 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. When pull requests are made, our tooling automation bot, OfBorg will perform various checks to help ensure expression quality.

The Nixpkgs maintainers are people who have assigned themselves to maintain specific individual packages. We encourage people who care about a package to assign themselves as a maintainer. When a pull request is made against a package, OfBorg will notify the appropriate maintainer(s). The Nixpkgs committers are people who have been given permission to merge.

Most contributions are based on and merged into these branches:

  • master is the main branch where all small contributions go
  • staging is branched from master, changes that have a big impact on Hydra builds go to this branch
  • staging-next is branched from staging and only fixes to stabilize and security fixes with a big impact on Hydra builds should be contributed to this branch. This branch is merged into master when deemed of sufficiently high quality

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.
