    Handle partition setups with overlapping partitions
    
    This is not supposed to happen but some disks are intentionally
    created like this in order to boot on as many different systems as
    possible. For example, see http://mjg59.dreamwidth.org/11285.html
    
    We handle this by simply just showing the partitions in order.
