I ought to have added, the way to check for overlapping is to compare the
cylinder numbers. Logical partitions can begin on the first cylinder of
the extended partition in which they reside, and can end on the last
cylinder of the extended partition. Logical partitions may not share
cylinders with each other, and primary and extended partitions may not
share cylinders either.
Also, all partitions have to be contiguous, as we do not deal with RAID
issues at this level.
