It’s cool to see academic research on build reproducibility, based on the Nix ecosystem.

Using historical data, we show that we are able to reproduce build environments of about 7 million Nix packages, and to rebuild 99.94% of the 14 thousand packages from a 6-year-old Nixpkgs revision.

Will you be using the results of this work to choose store paths for The Great Garbage Collection?

Yes, we’re adding those to our GC roots to keep the research reproducible.
