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But what if a package’s dependencies are out of date? These just stay out of date with their possible security problems as well.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.
Sorry for the late reply. In the 2 weeks I’ve still kept using it and I learned a lot! But a lot of my musings still stand, at least in my mind, but after thinking a little longer, a lot of the thoughts I had also apply to other distros as well.
To answer what you asked in final, a good hypothetical that might answer it is something like GNOME. If the nixos channel blew up in a doomsday scenario, I’d be stuck maintaining my packages myself, right? And I use the doomsday scenario, because the problems here apply for self-made packages as well, but it’s easier for me and maybe others to wrap their head around the problem I’m getting at. So with GNOME, I’d have to update every single dependency manually in my nix files. With something like Arch/Alpine I could just have those files, and they have these really neat scripts where I can just bump the version, and it’ll download, set the hash up, and bump the version all for me. With Nix there are no such tools. I can’t just automate the process, nor is it feasible to do this type of thing manually. As new features are added, so are new options needed to activate those features. And yes, although in this scenario, I would probably just opt to not add these options and set it up myself, when making a package for the general public this isn’t the case. If GNOME adds a feature (idk why I picked GNOME I haven’t used it in like 5 years) to have extensions managed by the package manager, I’d have to add an option for what extensions are needed and all that. And this is a lot of work, at least as far as I know. The extensions would also have to be packaged.
