I think OpenSUSE Tumbleweed has SELinux enabled now too. I’m not sure what you mean by all over the system, as I’m not that familiar with SELinux yet. I believe that Tumbleweed used to use AppArmor but recently switched to SELinux? I also believe that Leap (the stable version of OpenSUSE) still uses AppArmor.
Flathub not coming preconfigured
Huh, that’s odd. I’ve been test driving different Linux distros lately for my move away from Windows, and Tumbleweed was one of the ones I tried. KDE Discover in Tumbleweed had Flatpak options for software, and I’m pretty sure it was tied to Flathub and not a different repo like Fedora does. Maybe I’m misremembering? Or did you mean that it doesn’t have the Flathub application itself?
