Yes, I'm suggesting exactly that. There are standard mechanisms (configuration templates) that allow you to save and maintain these files directly inside the layers, and initialize the build/ directory using them. > In addition, is there a recommended way to manage debug/release build in > which case they share common configurations but also varies in lots of areas. First, you should carefully consider if you need separate debug/release builds at all. What would differ between them? Can you achieve the same thing in a single build by having different image recipes with their own set of packages and image tweaks? Can you configure your software to make those decisions at runtime when it starts (e.g. decide to run 'debug' or 'release' mode depending on what is written into a target configuration file)? If you do need two different builds (which will double the load on your CI), then you should make two different distributions. They need not be entirely separate: they can share almost everything in a common .inc, and only a few tweaks in the top level distro.conf file. Then local.conf only needs to set DISTRO to choose one or the other. Alex
