By the way, you *can* control the allocation of partitions down to the
sector level with parted, as well get the starting locations and
sizes of existing partitions (and free space) in sectors, if you want
to do so.  For example:

   parted /dev/sda unit s print free
   parted /dev/sda unit s mkpart primary ext2 100 999

etc.
