+ *        reside on the same volume as the loaded kernel image.
  *
  * The recommended way of loading and starting v1.0 or later kernels is to use
  * the LoadImage() and StartImage() EFI boot services, and expose the initrd
  * via the LINUX_EFI_INITRD_MEDIA_GUID device path.
  *
- * Versions older than v1.0 support initrd loading via the image load options
