Thats not true (and I've used tmpfs for tmp for years, so I'm speaking
from experience)— tmpfs is backed by swap on demand. Just add the
space that you would have used for /tmp to your swap.
The *default* limit for tmpfs is half of physical RAM (swap is not
counted). So *if* tmp-on-tmpfs is left at the defaults then
increasing physical RAM might be necessary. I haven't bothered to
look at how tmp-on-tmpfs is implemented in systemd though.
