You are using `survives reboots' as a proxy for `on disk'; and using
`on disk' as a proxy for `has enough space for large amounts of data'.
I don't think this is a good approach.
It's true that /tmp has traditionally been smaller than /var/tmp,
partly as an accident of partition and filesystem layout.
As a practical matter, there are big performance gains to be had from
not requiring across-reboot (and, particularly, across-crash)
persistence.
Perhaps the right answer is instead that we should simply configure
more swap by default ? (IIRC tmpfs data can be swapped.)
