/tmp directory not empty after install, systemd complains on boot like this : systemd[1]: tmp.mount: Directory /tmp to mount over is not empty, mounting anyway. As /tmp is a mount point for a volatile tmpfs, this directory should be empty after installation. Any files should not be here in this directory. Assigning to Mageia tools maintainers. Workaround: Mount your root partition from a live CD/USB, and remove files/directories present in /tmp directory. Mitigation: systemd mounts anyway a /tmpfs on this directory but complains.
