Comment (by stippi):
I remember seeing some code which does a plausibility test and refuses to
accept the partition layout in Haiku, for this above case exactly. I don't
see how Haiku could properly check this case, since partition layout
scanning happens independent of contained file systems, so the partition
scanning would not know that the file system contained in one of the
overlapping partitions has an internal size that removes the overlap. As
soon as you initialize this partition with another file system, you'd have
a problem. Invalid partition maps are just bad. What should happen if you
have a partition that completely lies within another partition?
