Who here uses a less popular Linux distribution? What made you choose it?
Hey fellow Linux enthusiasts! I'm curious to know if any of you use a less popular, obscure or exotic Linux distribution. What motivated you to choose that distribution over the more mainstream ones? I'd love to hear about your experiences and any unique features or benefits that drew you to your chosen distribution.

It all began with Nix software build system and package manager; they needee a way to build, compile software in a reproducible way. That is, if it builds on my machine, it should build on yours too given some constraints. Then they build a whole package repository for such sofware or package definitions, Nixpkgs, that can be build or retrieved using Nix package manager. Nixpkgs grew to be a repository for enabling runnig an GNU Linux OS on it: NixOS. It is declarative in the sense you write what it should contain like packages and behaves like system services. For example, see https://git.sr.ht/~misterio/nix-config.
Atomic in the sense that when you want to change system's configuration or state, everything should suceed in that update, otherwise fails; it is everything or nothing. This enables storing previous and current system revisions, so can rollback to previous state.
Nix plus things like flakes, nix shell, enables a build inviroment akin to containers, but much better, correct, and flexible.
Haskell is just an ecossytem Nixpkgs support.
May I ask what does .nix files do? I have joined unixporn community,and when I look into the dotfiles of some nix os user,their config are all written in nix rather than .conf or some other prevalent files. Should I learn nix if I want to use nix os? Or can I config my apps such as waybar in a way just like other systems (such as arch)?
Nix files are Nix [function] expressions to declare and set your system; there are many options you can set for example. You just need to learn a few chapters of https://nixcloud.io/tour/ and https://nixos.org/manual/nix/stable/language/, also modularization using imports.
For user/de configuration, you can either do the usual way or use home-manager.
You should have some understanding of the nix language to use it, but I wouldn't worry too too much.
I would also start by installing nix and home-manager on top of whatever distro you already use. For some config, you need to specify things in nix, but for things in home-manager, for example, you can usually either use nix or point to a toml or conf or whatever file.
