     In conjunction with a fixed and 'fits all' partition alignment the
     major design focus is maximum performance for the installed image
     (vs. minimal size).

     Because of the chosen default alignment of 1MiB there will be
     (1MiB - 512B) unused disk space for the MBR and also the same
     size unused in every partition.

     Assuming that 512 byte blocks are used, the resulting layout for
     extended partitions looks like (blocks offset in extended
     partition given):
-           0: MBR - 2047 blocks unused
