      Special "system_area=/dev/zero" causes 32k of NUL-bytes.  Use this
      to discard an MBR which eventually was loaded with the ISO image.
+     *partition_offset=*2kb_block_adr causes a partition table where the
+     first partition begins at the given block address. This is counted
+     in 2 kB blocks, not in 512 byte blocks. If the block address is
+     non-zero then it must be at least 16. A non-zero partition offset
+     causes two susperblocks to be generated and two sets of directory
+     trees. The image is then mountable from its absolute start as well
+     as from the partition start.
+     Preliminary restrictions: Non-zero offset works only with blank
+     output media and implies -compliance no_emul_toc.
+     *partition_sec_hd=*number gives the number of sectors per head for
+     partition offset. 0 chooses a default value.
+     *partition_hd_cyl=*number gives the number of heads per cylinder
+     for partition offset. 0 chooses a default value.
