So for a 15.2.5 cluster that's being converted to Cephadm, Cephadm
should use quay.io from the get-go. And it does, but only for "cephadm
adopt".

It does because you specify the container image on the command line in the adoption process.

When you do an "ceph orch upgrade --image
quay.io/ceph/ceph:v15.2.15" before deploying new RGWs and MDSs you
set the new default image for cephadm. No "real" upgrade will be
performered as the adopted containers already are running on this
image.

Yes, that's an idea. But it's also *very* counterintuitive, don't you agree?

I totally agree. But containers and automation are the future. And who could have thought about that the default container image registry would change or that Docker hub turns into an unusable repo. Not to become sarcastic here…
