Source: iproute2 Version: 3.16.0-2 Severity: wishlist Tags: patch User: reproducible-builds@lists.alioth.debian.org Usertags: timestamps X-Debbugs-CC: reproducible-builds@lists.alioth.debian.org
Hi! While working on Debian's “reproducible builds” effort [1], we have noticed that iproute2 doesn't build reproducibly. Documentation files (.dvi and .ps) contain timestamps of the build time. The attached patch prevents that the timestamps get embedded, which allows building iproute2 reproducibly. Regards, Reiner [1]: https://wiki.debian.org/ReproducibleBuilds
