John, Interfaces of a host carry enough information to be used to make routing decisions - that's the core idea of host and router-side VRF implementations. Network spaces as of now do not help you to solve routing problems in any way unless you have one big L2 network and "routing" is done

There is a scenario where a real rootfs is located on a bcache device, however, for that we need to register a bcache device at the initrd stage which already happens now. Then we'd locate a file system on it and do pivot_root and so on. The bcache naming, I believe, is not guaranteed at this
