On #249636 I had to manually run the updaters for hardened & libre kernels. The cause was that `update-rt.sh` suddenly broke. Because I didn't want to inhibit other kernel updates because of a rather niche variant, I decided to move forward temporarily and take care of it later. One issue was that the script failed silently, i.e. I only saw that the script terminated early from my prompt. This is fixed now by making each niche kernel updater print its exit code code if it failed. Also, errors are allowed, i.e. a broken `update-rt.sh` doesn't block `hardened/update.py` etc.. The issue itself is rather simple. When I updated the kernels in #249636, the sha256sums.asc for rt kernels[1] looked like this: 199bbb0cdb97ead22732473b95c8b2e8da62dfd71bde2339163119fb537a2b7c patch-6.1.38-rt13-rc1.patch.gz a1af54f6987e96de06cad0a3226c5b5a992b60df084a904b6b94ea247fb46027 patch-6.1.38-rt13-rc1.patch.xz 7bb68561787e46e3c433d9b514373ce368d587ac459b91df41934e70280d008f patches-6.1.38-rt13-rc1.tar.gz ee65336dd6ae0be398796e7b75291918811a23e10121dc09bd84b244b12402fa patches-6.1.38-rt13-rc1.tar.xz However, the script itself skips any RC versions of the realtime patches, so no releases were usable and the script failed. It's probably possible to use the overview over all releases instead[2], however that'd complicate the script notably. Anyways, since RT kernels don't bump to each patch-level release, I don't think it hurts too much if such an update is slightly more delayed. However if we want to fix this, I'd prefer this to be fixed by folks who care more about rt kernels than I do.

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

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 23.05 release
- Tests for unstable/master
- Tests for the NixOS 23.05 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.
