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.

As in declarative?
Yup it is. You configure your whole system by setting options in your config files, using a functional language. It's hard at first but with time you naturally get used to it
Where I got stuck before was in the number of packages that were not actually supported within Nix. I found the documentation very frustrating, but the community very welcoming.
