From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

Better than Docker in terms of reproducibility. While Docker containers are usually more or less reproducible, Docker images are not as the Dockerfiles depend on lots of external state such as the repositories of the distro used as a base image. This is also partially true for NixOS, but it's far more realistic to pin a version of nixpkgs (the Nix(OS) repository) than do the same with Debian repositories. The new Flake format even provides a way to pin nixpkgs by default.
