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.

What the hell is an immutable OS?
Base system is not changeable. you install user apps etc and those are separate from the root system that remains identical.
Immutable is awesome. The user instead uses flatpak, snap, and/or nix to install their packages and apps. If you want a mutable environment, you can use containers and their many system integration tools like distrobox.The system has rollback functionality thanks to ostree, abroot, or similar technologies, so in case an update goes awry, you can roll back to a previous working image. Update anxiety no longer exists for me
This video on steam os which is also immutable went over it: https://youtu.be/gwUf8pwoA5U?si=RlbN0pDnAgEGa-uf
