Instead, NixOS uses the Nix package manager, which is more similar to npm or Gem. With NixOS, you simply declare what you want your system to look like, and the operating system takes care of making it happen. This means you don’t have to manually handle the installation and maintenance of packages.

One of the most appealing aspects of NixOS is its ability to roll back system updates. If you find that an update causes issues with your workflow, you can quickly return to a previous state using the boot menu. This rollback feature acts as a safety net, protecting you from updates that might otherwise cause problems and giving you the confidence to update without fear.

How to use NixOS system configuration features

NixOS also streamlines system configuration by centralizing it. Instead of dealing with scattered configuration files as you might in other distributions, NixOS consolidates configurations into a single file or just a few files. This makes it much easier to control versions and replicate systems, which simplifies the setup and recovery processes. Watch the fantastic tutorial kindly created by Tris at No Boilerplate to learn more about the NixOS and how you can easily configure your system and move these settings to others.
