On most systems, /tmp isn't a RAM-only file system. It's usually
mapped to a physical disk of some kind.
That said, a short-lived temporary file will quite frequently never
touch the hardware at all. If the file is written, used, closed, and
unlinked quickly enough, the kernel will never feel the need to sync it
to permanent storage.
This, of course, is more of a thing for an operating system support list,
not a bash support list.
