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.

If you install one of the Fedora Atomic distros e.g., Silverblue, you can rebase to other atomic distros e.g., Bazzite very simply with a single command and reboot.
Oh interesting, I may need to look into atomic distro more. As of now I don't understand what are features, pros/cons. I'll read up but it's definitely looking like way forward for me. If u have resources please link them.
The basic idea is read-only system files with flatpak for apps. A 'rebase' more or less downloads another system image to boot into. You can even rollback to prior images i.e., rollback to Silverblue.
The Fedora project explains it better and has additional resources here: https://docs.fedoraproject.org/en-US/atomic-desktops/
Thanks
