Yup. That’s basically it. AppArmor isn’t a slouch either, but SELinux works well and is well-tested on Fedora. It’s a pity. I do think that SELinux > AppArmor, so if security is a serious concern of yours, then it’s worth considering Bazzite over Nobara. If, however, security is a top priority of yours, you might even consider secureblue. It’s not great for gaming though 😅. At some point, hardening clashes with performance gains…
