[Nexus 6P Q&A, Help & Troubleshooting] lrvick:
So some more info that might be useful.

I mounted the AOSP built image (system-aosp.img) and the image found in angler-mdb08m-factory-dbc17940.tgz (system-google.img).

I then searched for all files that exist in system-google.img but do not exist in system-aosp.img.

> for file in $(diff <(find system-google/ -type f -o -type l | sed 's#^[a-z-]\+/##g') <(find system-aosp/ -type f -o -type l | sed 's#^[a-z-]\+/##g') | egrep '^<' | sed 's/^< //g'); do ls -lahgG --time-style=+"" system-google/$file; done | column -t
