Reproducible OpenWRT

" write_page "

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 has a lot more information, eg. why this is useful, what common issues exist and which workarounds and solutions are known.
" write_page " Reproducible OpenWRT is an effort to apply this to OpenWRT. Thus each OpenWR target is build twice, with a few varitations added and then the resulting images from the two builds 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.

" write_page "

There is a monthly run jenkins job to test the master branch of openwrt.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_openwrt.sh in a Debian environemnt 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 very much appreciated!
