I don't exactly know what kind of history importing you do, but why don't you import the whole branch from the previous repository if you retained original git hashes? > Also importing the same tarball twice (under different names) should > produce the same delta. > > In general, reproducibility is a good idea, and pristine-tar is one tool > used here - so it would be nice if it worked itself reproducibly. > > Andreas I'm not sure there is anything beyond "aesthetic reasons" to have deltas reproducible. Yes, it would be nice as you said, but the goal of pristine-tar is to create reproducible tarballs, not its internal state. Moreover, it is likely that internal delta version of pristine-tar and pristine-gz will change soon [1] and in the long-term it is impossible to keep the deltas reproducible. I'll keep this open, though. Tomasz [1] https://bugs.debian.org/808813
