Source: aboot Version: 1.0~pre20040408-4 Severity: wishlist Tags: patch User: reproducible-builds@lists.alioth.debian.org Usertags: timestamps locale X-Debbugs-Cc: reproducible-builds@lists.alioth.debian.org
Hi! While working on the "reproducible builds" effort [1], we have noticed that aboot could not be built reproducibly. It has a copy of the docbook2man-de-spec.pl script from docbook-utils, which doesn't support SOURCE_DATE_EPOCH yet, so the timestamp embedded into manpages varies with locale and build time. The attached patch fixes this. Regards, Reiner [1]: https://wiki.debian.org/ReproducibleBuilds
