An immutable OS is fixed and mounted non-writable. Every update you get, every program you install is handled on top of it via containers or filesystem overlays so the underlying OS is untouched. Basically the same concept you know from smartphones or other devices with a "reset to factory settings" function. No matter how hard you screw up your system, you can always reset to the base OS, either by granulary deactivating things installed on top, or by a reset to the working base OS.
That's interesting. Thanks.
So how are OS updates handled, they are not written into the main OS?
They are written but don't replace something in the read-only OS. They are just overlayed, so once removed the original is still there. How they do it differs. There are actual overlay filesystems for the job, or some use btrfs where all subvolumes behave mostly like virtual partitions (and copies of a subvolume only take space for changes of the original).
