I think you may be conflating the notion that ubuntu or rhel/cent can be
updated w/o any issues to applications that run atop of the distributions
with what it means to introduce a minor update into the upstream openstack
If jobs could execute w/o a timeout the tripleo jobs would have not gone
red. Since we do have constraints in the upstream like a timeouts and
others we have to prepare containers, images etc to work efficiently in the
upstream. For example, if our jobs had the time to yum update the roughly
120 containers in play in each job the tripleo jobs would have just
worked. I am not advocating for not having timeouts or constraints on
jobs, however I am saying this is an infra issue, not a distribution or
distribution support issue.
I think this is an important point to consider and I view it as mostly
unrelated to the support claims by the distribution. Does that make sense?
