  • AIX formatted disks do not always have the MSDOS 55aa signature.
    This happens e.g. for unbootable AIX disks.

    Up to now, such disks were not recognized as AIX disks, because of the
    missing 55aa. Fix that by inverting the two tests. Let's first
    check for the AIX magic strings, and only if that fails check for
    the MSDOS magic word.

  • The MSDOS/MBR partition table includes a 32-bit unique ID, often referred
    to as the NT disk signature. When combined with a partition number within
    the table, this can form a unique ID similar in concept to EFI/GPT's
    partition UUID. Constructing and recording this value in struct
    partition_meta_info allows MSDOS partitions to be referred to on the
    kernel command-line using the following syntax:

    root=PARTUUID=0002dd75-01
