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.

Because the nix package manager places all system packages under
/nix/store/uniquehash-packagename-version/Where the unique hash is obtained via a Merkel tree of all the inputs. So in particular, binaries and libraries exist underneath those directories, not in the places you would expect from FHS.
In order to make the system actually work, environment variables are set up and executables are patched to refer to specific paths within the Nix Store.
