Reproducible builds enable anyone to reproduce bit by bit identical binary packages from a given source, so that anyone can verify that a given binary derived from the source it was said to be derived. There is a lot more information about reproducible builds on the Debian wiki and on https://reproducible.debian.net. The wiki explains in more depth why this is useful, what common issues exist and which workarounds and solutions are known.

Thus each coreboot.rom is build twice (without payloads), with a few varitations added and then those two ROMs are compared using debbindiff. Please note that the toolchain is not varied at all as the rebuild happens on exactly the same system. More variations are expected to be seen in the wild.

Thus the resulting debbindiff output is not nearly as clear as it could be - hopefully this limitation will be overcome soon. Also please note that the toolchain is not varied at all as the rebuild happens on exactly the same system. More variations are expected to be seen in the wild.

There is a monthly run jenkins job to test the master branch of $PROJECTNAME.git. Currently this job is triggered more often though, because this is still under development and brand new. The jenkins job is simply running reproducible_$PROJECTNAME.sh in a Debian environment and this script is solely responsible for creating this page. Feel invited to join #debian-reproducible (on irc.oftc.net) to request job runs whenever sensible. Patches and other feedback are also very much appreciated!
