Fedora and Open Subsa Support New Can Partitioning

Both fedora and open sousa do this where the home is a separate sub volume so that you can reinstall while keeping your home data. It's just in both installers, it's not quite as exposed as it should be. I'm totally down with the cold storage on Mars idea. Why not send five to 10 exabytes of data to Mars or to the moon via blue origin? That would be a little hard since high density data retrieval will get harder over time. But if it was reasonable to transmit it, I think about an odd amount of people out there are unprepared for how they're going to fade away digitally.
