It’s worth noting that this is precisely the kind of thing that the OCI model avoids entirely. You don’t *upgrade* a container, you create container images from a description, you create container instances from images. The issue of uninstalling things in a container never arises, because you simply destroy the container and create a new one and import persistent data as volumes. dch@, dfr@, and others have done phenomenal work to enable jails as the isolation mechanism for OCI containers and pkgbase is a key part of making this useful.
