Katello nightly pipeline failed:


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.
