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 an app via the built in package manager, yep, you’ll have to restart to update the system image, but for most apps you'll need (and don’t require deep system integration), you could just use appimage, flatpak or snap, which will all work without a restart. I’ve actually been using immutable distros for many times I’ve used Linux, and once you use it, it’s easy to get used to it unless your use case would work better on standard Linux.
Also, I don’t follow much if the kernel hotswapping feature news, but I do know that for these immutable distros, a pretty great feature is that you can just rebase the entire distro via a single command if you’d like, and you’ll keep all user data. I’ve actually done it on one of my spare laptops, rebasing from fedora kionite to bazzite linux, and it wasn’t awfully fast, it took an hour or so, but I find it impressive nonetheless.
That's really neat. Maybe a new breed of distrohopper will be born.
