RFC on Cloud Images: Make /tmp a tmpfs

As for "making available": you can append "none /tmp tmpfs defaults 0 0"
to /etc/fstab, as already mentioned. But if modifying fstab is
impractical/unsafe for some reason, the following also works:

  systemctl link /usr/share/systemd/tmp.mount

which is just a glorified way of doing

  ln -s /usr/share/systemd/tmp.mount /etc/systemd/system/tmp.mount

Conversely, disabling this would just be

  systemctl disable tmp.mount

or

  rm -f /etc/systemd/system/tmp.mount
