What if you just use distrobox in the future? You can use debian/ubuntu with it on whatever system you use. On my fedora silverblue installation almost everything is seperated from the OS. I barely touch the OS. It doesn’t really matter if I’m on silverblue, microos or vanillaos. I want to switch to microos because it comes with firefox as a flatpak ootb and other minor things. It’s jist not worth it anymore to switch the distro
