The 16.2->17.1 FFU process for Ceph/HCI depends on ceph-ansible from the RHEL-8 undercloud. In the case of OSPdO, the tripleoclient container image replaces the undercloud, therefore we also need a 17.1-RHEL8 tripleoclient image to be built.
Alternatively, could the required ceph-ansible bits could be included in the RHEL9 tripleoclient image? We need a way to get ceph-ansible (from rhceph-5-tools-for-rhel-8-x86_64-rpms e.g. [1]) to upgrade the RHCSv5 on the 16.2 HCI system to RHCSv5 and then manged by cephadm (that newer ceph-ansible has two playbooks to do that).
