Want to try something a little different? Bazzite was recently announced as a custom Fedora 38-based Linux image designed to bring the best Linux gaming to PCs and Steam Deck.
I asked the same question when this was posted elsewhere, and the answer that I received is that it is based on the immutable os spin of Fedora, so this is immutable as well.
Saw something about this days ago and couldn't find it. Definitely saving this post so I do not forget what this distro is called, again. Definitely wanna try this out via dual boot or VM in the future on a more powerful device than my current desktop and laptop.
