Indeed it appears that the initramfs is feature equivalent for all
releases back to Trusty (where this was first enabled).  It seems
sensible to turn this off.  However, lets do that in xenial first and
look for fallout.

Bug description:
  In Trusty I see a big delay while the kernel boots that I did not see back in Precise.
  Some people have been experiencing this in Saucy too, so I don't know exactly when it started happening.
  Excerpt from dmesg:
  [    3.740100] Switched to clocksource tsc
  [   14.208118] PM: Hibernation image not present or could not be loaded.
  [   14.208885] Freeing unused kernel memory: 864K (c19ac000 - c1a84000)

  The exact messages above don't matter, they are different on different boots or on different machines.
  It even happens with e.g. 
  $ sudo kvm -m 768 -cdrom trusty-desktop-i386.iso

  My current kernel is
  Linux server 3.12.0-7-generic #15-Ubuntu SMP Sun Dec 8 23:42:09 UTC 2013 i686 i686 i686 GNU/Linux
  ...but the exact version, maybe from 3.8 to 3.12+, shouldn't matter, just run `dmesg` yourself and check if there's a big delay there.
