hydra VS distrobox

See https://github.com/NixOS/hydra/issues/838 for making content-addressed derivations supported by hydra.nixos.org. At that point, we can actually try out the XP feature at scale.

Also see https://github.com/NixOS/nix/issues/8919 for this accepted RFC

Once those things are done, we can get back to merging in the IPFS code.

Now that there is an Nix team and I am on it, there is much, much less of an issue of these experiments being caught in limbo :).

Nix is pretty cool, and I would say comparisons to Earthly are apt. I may tackle that in a follow-up. If you did a monorepo setup written in nix and then used something like Hydra for building, it might be a pretty nice solution.

Nix seems great for build servers. This is a great introduction to the motivations behind it.

I'm not sold on using it for managing developer environments (another use case it is often used for). It "solves" the problem that developers might be using different versions of libraries or compilers on their machines... but it comes at the cost of having to learn a whole new programming language, a configuration language, a whole new jargon, and workflow. It's a bit like using Docker as a development environment. It introduces a non-trivial amount of friction.

Some folks get excited about package management and configuration. Personally I don't care for it enough to over-come such a high learning curve. And I don't particularly like the workflow it enforces.

However it is pretty great for reproducible CI/CD systems like Hydra: https://github.com/NixOS/hydra

Somewhat related to this, is there a good way to install something from a flake inside the configuration.nix? For example, the hydra flake, since it includes many derivations for dependencies that are not part of nixpkgs (or are at the wrong versions).

Regarding the stability issue on a dev machine - you may be interested in playing with one of the immutable-os distros, such as SilverBlue (fedora based).

The high-level take-away is you can't break your actual OS since it's root filesystem is read-only, and you use "pet" containers (on docker, podman, whatever) to do your work in. Applications are either sandboxed via Flatpak, or installed/run inside your pet containers. If your pet container dies, you cry about it for a moment, and when you're ready you get a new one - your actual os and other containers remain unaffected.

I use distrobox[1] to create/run the pet containers.

Distrobox is a tool that enables us to try Linux distro CLI, including their package manager. This requires a containerization tool (e.g., Docker). In Windows, this can be achieved using WSL (Windows Subsystem for Linux)

I use containerized versions of things, ubuntu and chainguard images mostly.

You can always create containers with init if that's how you want to do that though. Some distros publish images that come that way: https://github.com/89luca89/distrobox/blob/main/docs/useful_...

Yes, you can do that but I've seen others use something like distrobox to run linux inside of SteamOS: https://github.com/89luca89/distrobox/blob/main/docs/posts/steamdeck_guide.md

For such cases you might use something like this: https://github.com/89luca89/distrobox

Btw #3: Depending on what the user is trying to accomplish, e.g. maybe to make WSL(2) itself more of a "subsystem" than a "container engine", using something like Distrobox or nsbox.dev can be a good idea (along with Docker or Podman in Distrobox's case; the other one uses systemd-nspawn).

1. Find here in "Containers Distros" section the distro image that you want to install ("Toolbox" versions are better because they are configured for Distrobox) and get it URL: https://distrobox.it/compatibility/#containers-distros 2. Use that URL to create Distrobox: distrobox create -i registry.fedoraproject.org/fedora-toolbox:39 -n fedora_1_39 3. Enter Distrobox fedora_1_39: distrobox enter fedora_1_39 4. You are already in Distrobox console. Look at the name in console, it should be include the container name. 5. To exit Distrobox: exit 6. If you run: distrobox list you will see all distroboxes on the system. You will also see that distrobox that we exited is still running. 7. To stop distrobox use commands: distrobox stop fedora_1_39
