It’s actually a a separate piece of proprietary software, packing is in this PR:

github.com/NixOS/nixpkgs

docker-sbx: init at 0.33.0

master ← Skyb0rg007:docker-sbx

opened 08:59PM - 25 May 26 UTC

Adds the Docker `sbx` cli ([docs](https://docs.docker.com/reference/cli/sbx/)). … This is proprietary software, so the derivation simply unpacks the tarball and fixes-up RPATHs. Note: the package includes downloads for AMD64 Linux, ARM64 Darwin, and Windows. As I only have a Linux machine to work with, the Darwin build is likely broken, and is marked as such. ## Things done - Built on platform: - [X] x86_64-linux - [ ] aarch64-linux - [ ] x86_64-darwin - [ ] aarch64-darwin - Tested, as applicable: - [ ] [NixOS tests] in [nixos/tests]. - [X] [Package tests] at `passthru.tests`. - [ ] Tests in [lib/tests] or [pkgs/test] for functions and "core" functionality. - [x] Ran `nixpkgs-review` on this PR.

If you want to test out the derivation before its merged, you can run:

NIXPKGS_ALLOW_UNFREE=1 nix profile add 'github:Skyb0rg007/nixpkgs/docker-sbx#docker-sbx' --impure

Otherwise give the PR a like! That can help get maintainers to pay attention, since I’ve been waiting for a few weeks now.
