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.

They're not that different from the classic nix files. Their main difference is that their inputs are always well-defined (as opposed to a channels registry, i.e. you can get totally different systems by reapplying a configuration when you change channels which doesn't change your nix file at all). A configuration is always exactly described by a flake.nix and flake.lock.
I mean there is more to it, but this is the primary motivation. What you would normally put into use case specific nix files goes into a flake's output section. The stuff in your input sections is what you can use in there.
