(e.g. making source tarballs, doing coverage analysis) to the Nixpkgs tree. This makes it easier to run build farm jobs locally since you don't need to check out the "release" tree separately. Also it means one less input to declare for build farm jobs. * Removed succeedOnFailure and separate logging of phases. Hydra doesn't need that. svn path=/nixpkgs/trunk/; revision=13388
