Setting and using the SOURCE_DATE_EPOCH variable takes care of most of the magic necessary. https://reproducible-builds.org/docs/source-date-epoch/ vpp-ext-deps packages after this change is being built with that date set to date of the last modification of the subtree (similar logic to deriving the "number" for the package version) For the rest of the packages, pinning the following three variables should result in bit-identical artifacts across multiple runs: export SOURCE_DATE_EPOCH=$(date +%s) export VPP_BUILD_HOST="buildhost" export VPP_BUILD_USER="builduser" Add a blurb in the docs describing this new functionality.
