Unfortunately not. The repository for the preparation of the post is at https://github.com/khinsen/reproducibility-with-guix/ but it doesn't contain the file 'guix-version-for-reproduction.txt'. > Is really the commit 769b96b62e8c09b078f73adc09fb860505920f8f used to > produce the Docker image listed in the blog post? Hard to say... I can't play with that right now because I am running jobs on my computer that eat all the memory. One question I have been wondering about is the possibility of grafts being an obstacle to reproducibility. Grafts are something I don't really understand yet, so I cannot answer this question. In particular, does a grafted package get a different hash from a package built with grafting disabled? Cheers, Konrad.
