Ordering dependencies only take effect if all involved units are started at the same time. This means the ordering relationship is ignored if networking.service is already activating by the time rdma-load-modules@infiniband.service pulled into the boot transaction. Seems like a misconfiguration issue to me. -- Saludos, Felipe Sateler
