No worries about directness, it's actually what I am trying to elicit so I can understand and hopefully help address the issues. I did come across a couple of mailing list posts from you mainly asking about newer k8s/etcd/flannel versions and also etcdctl inclusion (there was a workaround posted at the time but I note it's now in the image) . These threads are actually what prompted me to ask "what else?" to try and determine if Magnum had other needs here, e.g. the rpm-ostree issue you refer to below is the type of hint I'm after to try and ensure everything is tracked somewhere.

I was playing around with this earlier in the week and had some more success via a slightly different path, I'm in the process of attempting to re-produce on a clean system to ensure that (a) I didn't skip anything in the notes I took and (b) weed out any other setup that was peculiar to my system before I propose something against the docs.

Thanks, the hint that it regarded rpm-ostree was enough for me to find this:
Does that seem like the right issue? That in turn led me to this bug which appears fixed in F21, but I need to follow up to work out what if anything happened w.r.t. the second half of Colin's comment in the above bug (or whether it is still relevant):
Somewhat tangentially I was also wondering if there are specific version combinations of components (be they images, or the versions of specific components they contain) that are currently recommended/preferred for a given release. Obviously there is the custom image that is currently provided but I am thinking more for folks trying to roll their own etc. I didn't spot anything while poking around in the docs as yet but I may be looking in the wrong places. What I am thinking of is something like this but for the Magnum context:
