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But what if a package’s dependencies are out of date? These just stay out of date with their possible security problems as well.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 way NixOS is, the initial setup of all the different things you would want is incredibly time consuming and it has a very very steep learning curve. It was incredibly difficult for me to set everything up. I tried to make it work and then ran away 4 times now, each time starting from the configuration I’ve had so far, and building up on it. I still haven’t been able to perfect my configuration, and I’ve been on NixOS (this time) since mid-June. I haven’t been working on it actively, but I have done some work on it. NixOS is just too complex and too much for me to wrap my head around. Personally, I’m leaving it for something else, I’m thinking of Void, and I might go back to Arch for a while, I don’t know. Fedora seemed promising, but after the recent telemetry stuff, I crossed it off my list. Tumbleweed seems alright? I’ll see. But I totally get it.
I too think that NixOS is amazing. It is really unique (Guix is similar but not quite) yet it is very difficult to learn and maintain properly.
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.
I’m personally very happy with tumbleweed. It’s been very stable, and has the built in rollback feature on the off chance an update played bad with your system (I’ve only needed to use it two or three times over the last few years across three different computers). Tumbleweed also integrates super well with plasma.
