    Lets say I have a single drive dual boot system. The 1st two primary
    partitions are Windows. The rest of the partitions on the drive are for
    Linux. The 1st primary (C:) is full. The second (D:) is barely used.
    I buy a new drive and, using a partitioning tool (e.g. PartitionMagic),
    I create a new primary on the second drive and copy all my stuff from
    the 2nd partition on the 1st drive to it. I delete the 2nd partition on
    the 1st drive and expand the 1st partition into the new free space.
    Now, for Windows, my C: and D: drives are intact and C: is no longer
    full. D: is on my new drive. However, for Linux, /dev/hda3 has become
    /dev/hda2. With the LABEL= approach the system will still boot. With
    hardcoded devices it wont.

    It doesn't take much of an imagination to come up with other scenarios
    that would be even more disruptive to the partition numbers. For
    example, re-arranging primary and logical partitions because one needs
    to adjust the space allocations or the system layout. Basically, the
    LABEL= paradigm gives you a level of indirection for devices -- a
    symbolic name instead of a hardcoded device address. This is generally
    considered a good thing and a more flexible approach to system design
    and administration.
