Right, the common hardware we should cover very well, even with a host-only initramfs. People who are able shuffle disks from one hardware to the other will be able to create a generic initramfs, either before moving things around, or with the rescue system on the new one. We still do not encode any disk location/property/serial number/path into the initramfs, and we will be able to find the disks/rootfs, even when we move the disk(s) around. Because people mentioned that: none of that was true for Windows, which is very picky about any topology or driver change regarding the disk. A simple port change or haredware reconfiguration on Windows often rendered the disk unbootable, even on the same machine.
