Title:
  [regression] Mir hangs and then crashes due to reading from
  /dev/random

Status in Mir:
  In Progress
Status in Unity System Compositor:
  In Progress
Status in mir package in Ubuntu:
  Confirmed
Status in unity-system-compositor package in Ubuntu:
  New

Bug description:
  cookie_factory attempts to read data from /dev/random at boot, and
  blocks until it has enough random data or timesout after 30 seconds.

  How I can reproduce
  1. Run the Unity8 greeter as a mir server
  2. Reboot

  Expected behavior: Greeter is displayed as mir && USC run happily
  Actual behavior: Mir throws an exception after 30 seconds

  Work-around:
  Before logging in, move the mouse around lots, for at least 20 seconds. And after logging in, while you're looking at a black screen, move the mouse around furiously. This will populate the kernel entropy pool sufficiently to avoid the hang and crash.
