DJ has been hacking on free software since I was still at school, so
no, he's not trolling.

And that's a really bad idea, which I always turn off in any computer
or server I manage.  Limiting /tmp to using RAM + swap and having it
erase at reboot is pointless additional complexity.  This caused us to
go through countless lines of code deciding if a temporary file is
"small" (how small? don't know!) and whether it should live in /tmp or
/var/tmp for people who have to suffer this configuration.

Filesystems already use RAM for caching when necessary, and I want
temporary directories with a controlled lifetime, not "whenever the
power happens to go off".  Plus more typing.

People use their systems in different ways.
