NixOS

I started using NixOS in September 2024. Before that, I had been using Arch Linux since 2021.

There were several key reasons why I decided to switch from Arch Linux to NixOS, but the main one was its declarative configuration and reproducibility. With NixOS, I can define my entire system setup in a configuration file (using a flake), making it effortless to replicate or restore my environment across multiple machines.

Additionally, using Home Manager, I can manage my dotfiles in a declarative and reproducible way. This means my user environment, including installed programs, shell settings, and even theme customizations, is version-controlled and easily portable.

While installing programs in NixOS can be a bit more complex compared to Arch Linux’s AUR, the benefits far outweigh the cons. The ability to have multiple systems with an identical configuration, roll back changes safely, and maintain a highly structured setup makes NixOS a powerful choice for long-term stability and maintainability.

Switching to NixOS has been a game-changer in how I manage my systems.
