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

[Ben Howard]

I am inclined to make the change here. The only problem that I can see
is that some smaller cloud instance types (*.micro on AWS, the upcoming
nano instance, GCE's micro, etc) this might be problematic.

Title:
  [ubuntu-cpc] please make /tmp a tmpfs in RAM

Status in livecd-rootfs package in Ubuntu:
  Triaged

Bug description:
  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
