Katello nightly pipeline failed:
https://ci.theforeman.org/job/katello-nightly-rpm-pipeline/554/
Looks like candlepin repoclosure is failing to clean up after itself?
As far as I can see, this was a side effect of forklift#867, where we dropped -b (become) from the Ansible invocation, thus now running the job as jenkins, not root, but the files on disk where still owned by root, so the cleanup could not wipe them.
