Bug Description

The ironic conductor provides a "disk" kernel parameter coming from the disk_devices option in the ironic conductor. The default value made the old ramdisk pick the first disk (sda, hda or vda) for deployment when no root device hints are provided.

With the switch over to IPA this logic is changed. IPA ignores this kernel argument and picks the smallest disk by default instead. It may result to the root device being moved on a simple rebuild. When cleaning is not enabled and config drive is present it may even fail the deployment, as the machine ends up with 2 config drives. We need to respect this kernel parameter for IPA.
