So what I understand uBlue is not to Fedora Atomic as Nobara is to Fedora?
Like, I can install Silverblue and get anything with rpm-ostree, but that is an overlay on the tree (like a git patch) instead of simple changing the files like on regular distro. Because of that swapping base of the tree to new or different version take computing time, so people are free to build custom base to their needs for convenience. And uBlue is a system to build those images easly. Do it get it right? 😅
