Bluefin/Bazzite/Aurora are immutable, atomic versions of Fedora. I’ll probably explain it wrong but they’re more secured than normal Linux flavors and you get several copies of your core system files, so when you inevitably fuck something up, you roll back to the previous version and undo your mistake.
I’ve only just moved over to Bazzite in the last 6 months or so, so I’m no expert, but it’s been a cinch to get most games running.
This is what I do for Bazzite and Mullvad.
I can’t get it to update through the repo while layered, so I’ve had to uninstall and reinstall using the new rpm each time. I keep saying I’m going to get around to troubleshooting it and then forget about it until the next update.
