**Describe the bug**

A clear and concise description of the unexpected behavior.

**Please be sure to use latest release of mergerfs to ensure the issue still exists. Not your distro's latest but the latest official release.**

The master branch is **not** to be considered production ready. Feel free to file bug reports but do so indicating clearly that you are testing unreleased code.


**To Reproduce**

Steps to reproduce the behavior. List **all** steps to reproduce. **All** settings.

Please simplify the reproduction as much as possible.
 - Unless it is dependenat on multiple branches, use a single branch
 - Reproduce with standard tooling if possible (touch,truncate,rm,rmdir,ln,etc.) Having to install 3rd party software will make debugging more difficult.
