There has been reasonable interest in the i686 builds for CentOS-7. And we also need some i686 components for the x86_64 multilib payload.
As a step-1 of the process, we are going to try and workout how much of the published sources built on i686, bootstraping the builds from Fedora-19/i686 and then rebuilding onto itself. The targets setup for that are c6.99.00 ( bootstrap from f19 ) and c6.99.01 ( build over itself ). Builds for c6.99.00 are now running, you can track status at http://lists.centos.org/pipermail/centos-build-reports/2014-January/ - with 9 build workers running, I expect the build round to be over in just over 24 hrs.
Once that is done, we will move to c6.99.01, and fix build failures and address specific issues. For the .00 builds, were just building blind to get some binary code into the build roots, the real QA stuff will only happen into the 01 builds and onto the 02 ones.
