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.

Bazzite is just Fedora KDE but immutable and optimized for gaming
what does immutable in this context mean? I am guessing you can still install software on bazzite
Basically, your OS drive (for the most part, there are exceptions) is read only. Every time your PC boots, it is initialized to your current OS image.
Yes, you can install software on it. For the most part, you default to flatpak, but it also comes preinstalled with distrobox that allows you to access any package manager from any distro you want. You can also install local RPM packages, but you have to update those manually.
They suggest you try to avoid it, but you can also "layer" packages onto your OS image using rpm-ostree. This basically adds the package to the image that initializes at boot. You usually only have to do this with things like VPN software. Maybe.
The result is an extremely stable OS. almost boringly so. Because updates and installed software aren't applied until the system is rebooted, it's essentially impossible for an update to break your install.
Also, rolling back to a previous OS image is trivial and takes like 30 seconds.
It's definitely an adjustment if you're already used to Linux, but it's really not that restrictive, it's just different.
Thanks for the explanation!
