Ironic is not only part of OSPd, but also a separate OpenStack product. Users of Ironic in overcloud could also benefit from these IPA images, but currently they depend rhosp-director-image (containing overcloud-full images unrelated to overcloud instances). Would be cool to move them to a package without dependency on overcloud-full and without director in its name, like rhosp-images-ipa.
