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

Status in Mir:
  Confirmed
Status in Unity System Compositor:
  Fix Committed
Status in mir package in Ubuntu:
  Confirmed

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: Play with the trackpad at bootup to generate entropy.
