The root volume in a systemdisk setup is handled in a special way. It is not allowed to setup a custom name or mountpoint for the root volume. Therefore the size of the root volume can be setup via the @root volume name. This check looks up the volume setup and searches if there is a configuration for the '/' mountpoint which would cause the image build to fail
