Right, on Debian/Ubuntu it's not too terrible (cloud-init's dependencies are usually the biggest issue there and we manage to avoid them by building our own images with no cloud-init), but on Red Hat derivatives there are a lot of deep operating system internals built on top of packaged Python libraries which simply can't be uninstalled cleanly nor safely. -- Jeremy Stanley
