Hello Barry,

thank you for your reply and clarifying the Fedora aspects.

Asking the right questions brings up to important details. While I was 
writing and trying to explain that the relevant test does use 
""tempfile.TemporaryDirectory" as a context, I realized that "PyFakeFS" 
is used in the back [1].

But that makes me wonder. On a "regular" system all tests are running. 
So the issue might exist because of a combination of 3 factors: 
shutil.rmtree(), PyFakeFS in a chroot/mock build environment.
