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.

Yep, I can for example rebase from Bazzite to Secureblue and keep all of my configs intact for say, KDE. So if a project goes fubar you aren't out of luck and need to reinstall and reconfig linux, its trivial to rebase/"swap distro", its a single command that looks like this
rpm-ostree rebase ostree-image-signed:docker://ghcr.io/ublue-os/bazzite-dx-nvidia:stableAll programs, files, configs, etc are intact in your home directory. I've swapped between user created spins for different DEs like Cosmic and so on, whats cool is its all preconfigured to run well under bazzites kernel. Image based upgrades are also very nice, theres inevitably config drift that messes with performance or updates can break your setup on other distros, image based means the devs tweak every interaction and push it all to you with the least effort possible on your part.
This is very cool, and I can suddenly see atomic being useful for certain circumstances. Won't be using it for my personal computer main driver, but hopping/resetting this is easily attracts me so. Thank you!
rpm-ostree is pretty nifty in general, it functions like git so it reapplies each of your configs over what the devs do each time you upgrade, leading to as little config drift and broken upgrades as possible. each upgrade feels like a fresh install imo
