​You're correct, theoretically. But in reality is best to not stick a dozen
services or apps in a single docker image. What's the point of using docker
if you're having a single container with everything in it? Eg: something
smells if you need to run a supervisor inside the container.

If we're talking about python packages managed by the os package manager
... there are very few situations where it makes sense to use them (eg:
pysvn is especially hard to build), but other than that? Plus it's easier
to cache some wheels than to cache some apt packages when building images,
way easier.
