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.
