Enable /tmp directoy in RAM/Memory

Situation:

The /tmp directoy is mounted as a filesystem

this leads to performance problems if the disc is not fast enough and on fast ssd it can lead to a shorter lifetime to to massive I/O operations on /tmp

Solution:

Enable tmp.mount via Systemd:

df -h /tmp
sudo cp /usr/share/systemd/tmp.mount /etc/systemd/system/tmp.mount
sudo systemctl enable tmp.mount
sudo systemctl status tmp.mount
df -h /tmp
