Consider returning /private/tmp instead of /tmp on macOS with std::env::temp_dir() #99608
Description
The first is a regular directory, the second is a symlink to the first. This can lead to software failing in strange and unexpected ways (especially during testing, with the tempfile crate or similar) if symlinks are forbidden, e.g. I recently encountered the case with SQLite
Since /tmp -> /private/tmp software that was already working correctly should not start to fail unexpectedly. Software that was failing/had to workaround this will start working correctly.
