In Fedora 18, /tmp is going to be a RAM filesystem, so we absolutely
must not create any sizeable files on /tmp.

In addition from a security POV, we must aim to *never* use /tmp for
anything at all

It would be good to do a thorough audit of the code to make sure
nothing is using the tmpfile functions without explicitly specifying
a directory path that is private to the OpenStack daemon in question.

Daniel
