Package: debhelper Version: 9.20150101 Severity: wishlist Tags: patch User: reproducible-bui...@lists.alioth.debian.org Usertags: toolchain fileordering
Hi! While working on the “reproducible builds” effort [1], we have noticed that some packages could not be built reproducibly because the maintainer scripts generated by dh_usrlocal would vary depending on filesystem ordering. The attached patch sort the directory lists to provide a stable output. [1]: https://wiki.debian.org/ReproducibleBuilds -- Lunar .''`. lu...@debian.org : :Ⓐ : # apt-get install anarchism `. `'` `-

Subject: [PATCH] dh_usrlocal: output dir list in a stable order
We now sort the directory lists in order to guarantee a stable output.
This was preventing some packages to build reproducibly.
