I proposed a WIP change for oslo.config [1] last week that would allow us to specify what services (e.g. nova-compute, nova-scheduler, nova- api, etc.) an option applies to. This came about because of comments on another issue where we found no one could say with surety what services needed an option in their configuration option (which in turn brought up questions about why those services needed the option). It was suggested I bring the idea up on the mailing list before we proceeded any further with it so here I am. I'm interested in two things. Firstly, I'd like to know whether generation of per-service configuration files is actually something others find problematic? I'm imagining this is annoying for operators and those working on deployment tooling but I've never got any hard data to back up that assumption. Secondly, I didn't see anything in the likes of cinder, nova or neutron but has anyone else already worked on something like this? For what it's worth, I did explain why I've gone with the approach I have in the commit message, but that doesn't mean there aren't other options I could be missing.

Sorry for any possible noise.
