It would be nice if we were able to modify sd-boot stub to export something more specific that ideally maps to a sysfs path. For example PCI_DEVICE_PATH, SCSI_DEVICE_PATH, SATA_DEVICE_PATH, USB_DEVICE_PATH, NVME_NAMESPACE_DEVICE_PATH, SD_DEVICE_PATH, UFS_DEVICE_PATH, EMMC_DEVICE_PATH or some such. That way initrd would be able to resolve better which block device to key off. Given that EFI device handle is passed to the kernel, doesn't kernel also know where it came from? or not?
