My immediate answer would be containers. I like using them to run services, I even have my developer environments in containers - so I don't pollute my system. And I even saw people working on "standalone containers" or "system containers" which are basically containers installed by DNF, started with systemd, having all the config files on the local filesystem, tracked by RPM. I also heard people talk about Flatpaks built out of modules - that might be a solution for desktop apps. RPMs... Well, if someone has an application on their server that doesn't run in a container, there are still RPMs on a traditional system. But would you install multiple versions stuff on that single system? Or would other things run in containers? And I'm just curious here, because I managed to use containers for basically everything I need. What about other people? So, not everything will probably be installable as RPMs on the same system at the same time. But I see the world is going to containers, and I'm thinking if not being to install all RPMs next to each other on a single system is still a real problem.
