Can you elaborate on what pulp2 users don't like about the "multi-layered" approach in pulp2? IIRC, pulp2 only supports the "override config" thing (which I agree, few users like) and not something persistent. I suspect that users don't like the pulp2 implementation but may find the more sophisticated profile concept appealing even with a precedence model. Not supporting a model where the importer attributes take precedence over the profile will likely limit the properties in the profile to just the proxy. This could be a more powerful feature. I'm imagining cases where users would find it useful for the profile to include properties beyond proxy URL (or other download properties). Perhaps even the download or sync policies. Who knows. I do recognize that we really only have a concrete use case for the proxy but seems short sighted to design what seems to be intended as a more general concept that would be so limited. I don't perceive a precedence model as being particularly complex. > > So my proposal is that we do not provide a way to globally set other importer > settings in Pulp 3.0.
