Title:
  zram-config terminates with status 2. zram swaps not enabled

Status in “zram-config” package in Ubuntu:
  Confirmed

Bug description:
  dmesg says:
  init: zram-config pre-start process (1047) terminated with status 2

  sudo service zram-config start works though.

  the whole dmesg reads:
  [    5.381143] zram: num_devices not specified. Using default: 1
  [    5.381145] zram: Creating 1 devices ...
  ...
  [   21.605734] Adding 1011288k swap on /dev/zram0.  Priority:5 extents:1 across:1011288k SS
  [   21.606373] init: zram-config pre-start process (1047) terminated with status 2

  num_devices should get calculated in the upstart script. The size is
  correct in that it's the same when started manually.
