/tmp is one of the weirder places in a system.

It is nice that FHS says it is not persistent across reboots, but if you
have a
workstation or server which is "never" (or at least, seldomly) rebooted,
the
directory can still fill up - and take away RAM from both oneself and
other
users.

tmpfs is not a RAM file system but a filesystem based on anonymous memory.
This
is how it has been implemented on SunOS un 1987 and I am _very_ sure it
works
the same on Linux.

In other words: if you have files that lay around in /tmp. this just eats
up
swap.

It can still fill up.

Correct. And today it can fill up your root partition preventing you
from login or update to your system. So what?

Well, so far it was not mentioned how big the tmpfs will be.
