Idea of this distro different Rpm-ostree mostly not supposed to use at all or used in rare case to install some system driver or etc packages ,everything else .to install software it supposed to use flatpak,appimages and toolbox(I prefer distrobox which possible to install either and work both using podman) to create containers in which will be small copies of OSes ,u can install any u need Debian/arch/Ubuntu/fedora and they would be mutable in container and not touching with binaries libs and etc main system.
