Bug description:
  ubuntu-seed / ubuntu-boot partition detection could be improved

  Currently in the initrd, snapd-bootstrap searches for ubuntu-boot /
  ubuntu-seed partition by label or by UEFI variable that was set by sd-
  boot.

  sdboot uses devicepath UEFI protocol to establish MEDIA_DEVICE_PATH,
  HARDDRIVE_DEVICEPATH, GUID, Signature aka partuuid that was used to
  boot.

  This is nice, but not unique enough. 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?
