And there we have it, the first community contribution via git.centos.org is now live.
Andreas Thienemann’s offered to test and do some work of the work around the i686 CentOS-7 builds; and has gone through to propose mock configs that allow the i686 tree to be bootstrapped. I’ve just merged his pull request, and pushed it to the builders. The entire distro churn for i686 is now running, with details at seven.centos.org and you can see the build reports published in realtime at http://lists.centos.org/pipermail/centos-build-reports/2014-January/thread.html
This should allow everyone to quantify the scope of work we might be looking at, if as a community, we decide to maintain a i686 tree + installer for CentOS-7.
