        START and END are disk locations, such as 4GB or 10%.  Negative values count from the end of
        the disk.  For example, -1s specifies exactly the last sector.
 
        'mkpart' makes a partition without creating a new file system on the partition.  FS-TYPE may be
        specified to set an appropriate partition ID.
