Enter RakuOS’s hybrid design in which everything installed through dnf is overlayed persistently over the bootc-managed base system.


Then what is? And which authorities endorses that view? Or…, is it perhaps possible to arrive at that definition by (logical) necessity? If no such authorities exist and if it doesn’t follow by necessity, then how is your definition anything but arbitrary?
