The implementation consists in adding a global instrumentation hook that registers which files are installed by each package. A limitation of the current implementation is that when a file is installed by a package A and then overriden by package B, the mechanism will assume the file was installed by package A. Suggestions to welcome on how to solve this in a reasonably simple way.
It's very well possible that I'm missing something, but I don't get why you need to save the list of all installed files.

Can't you just save the whole rootfs size before and after installation? It can be simply computer by 'du -bs $(TARGET_DIR)', and it's way easier to parse later. It would also take into account the change of size for overwritten files, for free.
Of course your approach collects more information, but I don't see these extra info used in the final graph.
The reason is explained a bit further in that cover letter: we only do
stripping and removing of redundant stuff in the finalize step, so calculating the size before that doesn't make much sense.
The alternative of repeating the finalize step after each package doesn't sound
very attractive either.
