nixosTests.cryptpad started failing recently. Investigating the issue shows that seccomp has become problematic during the init phase, (e.g. this can be reproduced by removing the customize directory in /var/lib/cryptpad): machine # [ 10.774365] systemd-coredump[864]: Process 756 (node) of user 65513 dumped core. machine # machine # Module libgcc_s.so.1 without build-id. machine # Module libstdc++.so.6 without build-id. machine # Module libicudata.so.74 without build-id. machine # Module libicuuc.so.74 without build-id. machine # Module libicui18n.so.74 without build-id. machine # Module libz.so.1 without build-id. machine # Module node without build-id. machine # Stack trace of thread 756: machine # #0 0x00007ff951974dcb fchown (libc.so.6 + 0x107dcb) machine # #1 0x00007ff95490d0c0 uv__fs_copyfile (libuv.so.1 + 0x150c0) machine # #2 0x00007ff95490d89a uv__fs_work (libuv.so.1 + 0x1589a) machine # #3 0x00007ff954910c76 uv_fs_copyfile (libuv.so.1 + 0x18c76) machine # #4 0x0000000000eb8a39 _ZN4node2fsL8CopyFileERKN2v820FunctionCallbackInfoINS1_5ValueEEE (node + 0xab8a39) machine # #5 0x0000000001cda5e2 Builtins_CallApiCallbackGeneric (node + 0x18da5e2) [...] machine # [ 10.877468] cryptpad[685]: /nix/store/h4yhhxpfm03c5rgz91q7jrvknh596ly2-cryptpad-2024.12.0/bin/cryptpad: line 3: 756 Bad system call (core dumped) "/nix/store/fkyp1bm5gll9adnfcj92snyym524mdrj-nodejs-22.11.0/bin/node" "/nix/store/h4yhhxpfm03c5rgz91q7jrvknh596ly2-cryptpad-2024.12.0/lib/node_modules/cryptpad/scripts/build.js" nodejs 20.18 rightly did not require chown when the source and destination are the same owner (heck, the script does not run as root so even if it is not blocked there is no way it'd work with a different owner...) For now just allow chown calls again, this is not worth wasting more time. Fixes https://github.com/NixOS/nixpkgs/issues/370717
Nixpkgs is a collection of over 100,000 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.
