Some packages may depend on python-setuptools, which is not installed and cannot be reinstalled on CentOS 6.x once yum has erased them, so use --skip-broken to avoid aborting. Also on this platform --downloadonly causes yum to return nonzero even when it succeeds, so ignore its exit code. Change-Id: Iaada39ae81e1e47fe9d0bedba80fd19e4e0e6f38
