An enhancement in RHOSP 9 allows agent drivers (drivers prefixed with "agent_") to deploy partition images.
This capability was added because all drivers in OpenStack Bare Metal Provisioning (ironic) should be able to deploy full disk images (these are images that contain a partition table with a bootloader, among other properties). This also includes partition images, which are images with a root filesystem.
As a result, agent drivers are now able to deploy partition images, as well as full disk images.
The steps for deploying partition images must be added to the RHOSP 9 Bare Metal Provisioning guide.
Assigning to Sandra for review.
