Cover letter [Buildroot] [RFCv1 0/4] Generating a graph of the size installed by each package
Quoted 8 lines · Thomas Petazzoni
Hello,
I gave a training this week, and one of the question I had was how to analyze the size of the things that are present on the root filesystem. And I thought that Buildroot was lacking a tool to help with this. Therefore, the following set of commits implement a script that generates a pie chart of the size contribution of each package to the target root filesystem.
Would certainly be useful in buildroot, your idea looks good.

To see an example of the generated pie chart, see:
http://free-electrons.com/~thomas/pub/buildroot/graph-size.pdf
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.
Can you not record the timestamp the first time you see the file and see if it has changed at the end. I appreciate a bash script to do this is going to be pretty hard.
Regards
Will
