Actual results: some of the fedora or centos builds are failing with device-busy during cleanup Expected results: successful build, regardless of the cleanup task. Additional info:
This is rather an issue in mock: Product: Fedora Component: mock I would recommend opening the bug there as well and put link here to track it.
The problem in mock is fixed now.
