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.

Immutable = Read-Only Root FS && Updates entire system image rather than individual files
Atomic = Updates as single transaction (all or no update) && Containerization w/ Rollback capability
This is quick summary from quick research pls correct where technically wrong.
If we're asking what people mean when they use those descriptors, then you're correct.
However, literally speaking, in this context, immutable only means read-only, and atomic only means that updates are applied all-at-once or not at all (no weird in-between state if your update crashes halfway through).
The rest of the features (rollbacks, containerization, and immutable meaning full system image updates) are typically implied, but not explicitly part of the definition.
I knew a real wizard would clarify sooner than later. Much obliged and keep up the good work anon!
That makes sense, bazzite is referred to as atomic (that's what I meant in the above comment about atomic being more appropriate, forgot to add that context though lol) specifically instead of immutable. Bazzite updates like you said and you can always roll back, thank you for the explanation!
