Hi Ross, thanks for clarifying that there are no dependencies between images.

So I could have the python-image build know which dependencies are already built into my OS image and therefore not include them itself? No. An image is a self-contained file system. About 50% of your image recipe isn't helping your goal of an image that contains a single package. What should be improved to achieve my goal of containing only the python3 package and as little dependencies as possible? I have to query your assumptions though: if you're going to have python3 in a filessytem that you mount when required, how are you saving space? That seems to be a misunderstanding. I want to keep the OS image as small as possible to reduce boot time. We only use python for some test scenarios, so it doesn’t have to be included in the OS image. I did some measurements and including python3 in the OS image increased the boot time by over 30%. So the idea is to have it separately, and only mount it, when needed.
