During setting up a ubuntu machine with TYPO3 Neos on a shared folder (NFS) I ran into below error while running the TYPO3.Media functional tests.

After some debugging I found this comment on php.net: http://nl1.php.net/rename#90025

This made me think it could be an issue that the rename() was called for moving the file from network storage to local storage. So I set the setting below to make sure that my Data/Temporary folder was also on local storage (see yaml file)

Now the rename() action was from local storage to local storage, and the error is gone.
