Persist /tmp permissions

Add to /etc/tmpfiles.d/[ hostname ] to enforce correct perms

echo "d /tmp 1777 root root -" | sudo tee /etc/tmpfiles.d/[ hostname ]

Or add to /etc/[ hostname ] (if you use it)

echo "chmod 1777 /tmp" | sudo tee -a /etc/[ hostname ]

Or create a systemd service to enforce it

sudo tee /etc/systemd/system/[ hostname ] <<'EOF'
