Bug description:
  Pasting disk_setup for cloud-config:

  disk_setup:
    /dev/xvde:
       layout: True
       overwrite: False
       type: mbr
  fs_setup:
    -device: /dev/xvde
     filesystem: ext4
     label: data
     overwrite: false
     partition: auto

  I want to attach and mount a /data disk on the VM using cloud-init so
  I just want to single partition 100% of the disk.

  Error while running the sfdisk command for partitioning the disk (please see attached file).
  OS: Ubuntu18

  How I repro-ed it outside cloud-init environment:
  1. Open XenCenter, add a new disk, say /dev/xvdc
  2. Run `/sbin/sfdisk --Linux --unit=S --force /dev/xvdc` and specify start sector as 0. Because from the cloud-init logs and source code, I figured that it was picking start sector as 0. Save it and see the error.
