This has come up in the past but we keep getting sloppy and not doing it. Directories should be configurable so that we can mock them out entirely during test runs. There is no reason a test case should affect "real" files and directories on the filesystem. They should be configured to write to temporary directories where permissions aren't an issue and the risk of affecting live data is minimized.

The following was seen by a pulp user trying to run the tests.

(tests that passed not included in this paste)...
