You can pass `init=/bin/bash` as kernel boot parameter through GRUB and
then copy the temporary files to a safe place. And that way will work
even if the computer was off normally. I once used this loophole myself
to save files which I had forgotten. However in general, /tmp is not
intended to have important data which is worth regretting.
