> maybe it's indeed time to let the system package management(apt,rpm,etc) just manage a solid BASE system, and let Flatpak etc to manage their own application sandboxes on top, kind of like dockers. This is kind of how immutable systems like fedora's silverblue, and suse's microos are setup. The base systems are still built with rpm, but for user packages you either use flatpak or stuff in containers via toolbox or distrobox. It's still possible to layer stuff on to the base image if necessary though.
