3.10. Disks and Partitions Configuration using Image Builder

Image Builder does not allow disks to be partitioned. The output types that have a partitioned disk will have a single partition and additionally any platform-specific partitions that are required to boot the system image. For example, qcow2 image type has a single root partition, and possibly a platform specific boot partition - like PReP for PPC64 system - that the image requires to boot.
