In general, the idea of being able to move between phases like that is
really cool. I don't have any experience with overlayfs, so I can't
comment on that detail.
I wouldn't say it's ever obvious where a reproducibility bug is
introduced, but many of them are timestamps, sometimes with an English
string attached, and that code is usually easy to find.
Thankfully, the Reproducible Builds project has a useful database of
bugs they've found:
