Specifically for the hosted-engine use case, I had the same suspicion, so I
patched Lago to use '--network' in virt-sysprep and added 'update' command
to ensure all hosts are fully up-to-date when deployed.
It did not solve the issue.

Generally:
1. Updating the images take quite some time, per run.
2. I agree every X months we should be updating the images. Every Q for
example. I've already discussed this with Gal. If CentOS would have
released a new baseline, that would have been more real life scenario, btw.
3. That being said, if you need a dependency, you need to depend on it, and
we'll pull it. We do not ask (I think?) to 'yum update' your system before
deploying oVirt.
4. There were, luckily, very few o-s-t only issues thus far. It may happen,
and we will run into those, but we have not so far encountered many. Some
we did not bother pursue, though are clear bugs (I remember an annoying one
with 'mount' command not getting back at all, etc.)
