[Bug 1533639] [NEW] [ubuntu-cpc] please make /tmp a tmpfs in RAM

[Dustin Kirkland ]

Public bug reported:

In Ubuntu, we clear /tmp on every boot.

As such, on servers, by default /tmp should actually be a tmpfs entirely
in RAM.

This has several advantages, mainly:
 * Performance - much faster read/write access to data in /tmp
 * Security - sensitive data would be cleared from memory on boot, rather than written (leaked) to disk -- important for encryption scenarios

** Affects: livecd-rootfs (Ubuntu)
     Importance: High

         Status: Triaged

** Changed in: livecd-rootfs (Ubuntu)
       Status: New => Triaged
