    Use kpartx option to update partition mappings
    
    Fix cases of 'mkfs' failing because the partitions never showed up. Partition
    mappings will now be updated instead of just adding them with 'kpartx'. That
    means that 'kpartx' will also remove devmappings for deleted partitions.
    
    Traceback of failing mkfs call:
