NixOS26.05
Your whole system, described in configuration.
What is NixOS?
NixOS uses declarative configuration and the Nix package manager to make system changes repeatable. Generations let you boot earlier configurations. It is especially useful for developers who want reproducible environments, but the Nix language and filesystem layout bring a learning curve. Declarative does not mean identical to an image-based atomic desktop.

Write the image to a USB stick and boot it as a live session to test Wi-Fi, graphics, sound, and suspend on your own computer. A browser trial on DistroSea shows the desktop, but cannot verify your hardware.
