Hi Kohsuke and Oliver,
In the past, there've been some problems since we didn't have a branch of packaging corresponding to the current LTS branch.
So I created JENKINS-44662 and
https://github.com/jenkinsci/packaging/tree/stable-2.60 for the upcoming LTS line.
Kohsuke, Oliver: OK for you?
Oliver: Could you take care of this for future baselines as part of creating the jenkinsci/jenkins branch?
Daniel
