Hi all,

I’ve been using NixOS for a while now (About a month now) and I’ve been loving it, but I’ve had some thoughts lately.

I understand that Nix(OS)'s claim to fame is the fact that packages are reproducible. All dependencies are versioned and all packages are rollback-able (although not sandboxed). With proper maintenance (nix-collect-garbage mostly), the problem with space is mostly mitigated.

But what if a package’s dependencies are out of date? These just stay out of date with their possible security problems as well. Not just that but it’s (nearly) impossible to actually do your own manual imperative editing of packages to solve a quick problem since everything is declarative.

Not just this, but Nix uses mostly its own configuration methodology, so isn’t this a maintenance nightmare as config files change and options are added/removed? Home manager is a prime example of this potential problem.

Plus more technologies being introduced on top of it to solve problems that seem already solved? (Flakes mostly come to mind).

I have come to the realiziation that, unlike a traditional distro like Arch/Alpine which I used previously, if maintenance dies I cannot feasibly maintain it myself, since it’s mostly “magic”. The upkeep of all the configurations plus all the dependency packages, and making sure each package compiles and matches the build configuration is a nightmare. I can barely do it with my own personal projects.

Anyways that’s kinda it just expressing thoughts about it. I do love Nix(OS) and plan to continue using it. It’s amazing, and its capabilities are matched by few to none, and from a user perspective it is an extremely seamless and simple OS. It’s mostly from a maintainer perspective that I had.

    The main problem with NixOS right now is, in my opinion, the scattered documentation. You often can’t understand a topic without cross-referencing the manual, nixos wiki, nixos search (and nixpkgs and some scattered personal blogs if you’re really unlucky). But if you stick around and adapt to this it’s very easy to do stuff that takes a lot of effort on other distros with a few lines in your config.

      While we’re on the topic: What’s a great resource to learn about flakes? I can’t seem to find a great answer that also shows why they are better and when.

        They’re still unstable and fully optional. When you’re at the point where you could benefit from flakes, you’ll know it. Ignore them for now.
        The most tangible difference to a NixOS user would be that they replace channels. If you’re contempt with channels, no need to rush to flakes.

        Hey, sorry for the late reply. I found the blog by xiaoso quite good, and this one also isn’t too bad. But I never found one true source which explained it satisfactorily to me. It’s probably best if you just browse through other people’s configuration and piece it all together from that. From what I understood, flakes have 3 main uses:

        1. They replace nix channels. If you want to switch between stable and unstable it’s pretty easy to do through flakes. Also, if you need any modules (like home manager or agenix, for encrypting secrets) you can simply import it as an import for your flake.
        2. You can “modularize” your configuration. You can describe multiple systems in a single flake so you can have your desktop and laptop be built from the same flake, but with different packages installed. This is the part that I use most and honestly find most useful.
        3. You can quickly have a development environemnt through flakes. You could use a flake per project, have all your dependencies as inputs in your dev flakes and never clutter your system with various dev tools

        Nixos is riddled with stuff that you just “have to know” which can be quite frustrating. The lon ger you stick with it, the easier it gets though.
