Unexpected Test Failure in test_du_no_dereference #5585
Description
I encountered an unexpected test failure while running cargo test, specifically in the test_du::test_du_no_dereference test case. The failure seems to be related to the use of symbolic links in the /tmp directory.
Error Output:

Steps to Reproduce:
In the project directory, run cargo test.
Additional Information:
- The error is consistently reproduced on local machines.
- The error does not trigger the repository CI, possibly due to differences in the filesystem (as discussed here).
