`nixos-rebuild-ng` explicitly don't allocate a pseudo-TTY for SSH because this causes lots of issues depending on the use case (for example, multiplexing multiple SSH sessions). Sadly not using a pseudo-TTY also cause other issues, like the fact that using Ctrl+C (SIGINT) doesn't kill the underlying process because SSH doesn't support it. We can't really start using pseudo-TTY unless we want to overcomplicate the code for parsing results (pseudo-TTY mangles the stdout/stderr together), so we need to handle killing the underlying remote process manually. This is what this commit does, when we receive a `KeyboardInterrupt` exception while calling `run_wrapper`, we will check if it is a remote process and send a `pkill --full` with the arguments (this should ensure that we don't kill other process, but we can't guarantee it). This assumes the user has `procps` installed, but I think it is a safe assumption since this seems to be a core package. Sadly nothing we can do if the user doesn't have `procps` installed, the good thing is that the worst that can happen is that we will silent fail and the process will stay in background until it finishes. Fix #403269.
Nixpkgs is a collection of over 120,000 software packages that can be installed with the Nix package manager. It also implements NixOS, a purely-functional Linux distribution.

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.
- Continuous package builds for unstable/master
- Continuous package builds for the NixOS 24.11 release
- Tests for unstable/master
- Tests for the NixOS 24.11 release
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.

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:
