I'd expect that when you need a proper rpm then you have to go through all the pain and build everything from scratch to make it perfect.
If you want to test something and debug, etc, you'd not build a full blown rpm anyway, would you?
Well, either way, if you'd have 15 minutes for me I'd appreciate you show me how it's being done today….
