This is required for qemu-img to support luks.
This was discovered when trying to fix a failing build with
python3Packages.oslo-utils on at least version 7.4.0.
Both (lib)gcrypt and nettle together with hogweed are fallbacks when
gnutls is not found and are not used despite the convoluted build script
suggesting it.
Configure output before this patch:
...
Crypto
TLS priority : NORMAL
GNUTLS support : YES 3.8.6
GNUTLS crypto : YES
libgcrypt : NO
nettle : NO
SM4 ALG support : NO
SM3 ALG support : NO
AF_ALG support : NO
rng-none : NO
Linux keyring : YES
Linux keyutils : NO
...
and after this patch:
...
Crypto
TLS priority : NORMAL
GNUTLS support : YES 3.8.6
GNUTLS crypto : YES
libgcrypt : NO
nettle : NO
SM4 ALG support : NO
SM3 ALG support : NO
AF_ALG support : NO
rng-none : NO
Linux keyring : YES
Linux keyutils : NO
...
This can be easily tested by building qemu-utils and running
qemu-img create -f luks --object secret,id=sec0,data=secret-passphrase -o key-secret=sec0 tmp.img 536870912
which is the command that failed in oslo-utils

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

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.
