It seems the current plan of record (after long discussion on IRC and
upstream ML) would be to enable /tmp on tmpfs on vivid+1 (it's quite
late to do it this cycle, even if we switch to systemd by default).

Upstream ML reference after another approach with a service to disable
tmp.mount: http://lists.freedesktop.org/archives/systemd-

Title:
  Cannot boot with newly installed systemd if /tmp/ is filled with files

Status in systemd package in Ubuntu:
  Triaged
Status in upstart package in Ubuntu:
  New

Bug description:
  On a new lubuntu 14.10 install, after installing a bunch of new
  packages, I rebooted the machine and it stalls on startup. It stays on
  the four dots of plymouth (not the graphical version).

  After trying various options in rescue mode, I end up understanding
  that the boot system has switched to systemd by looking at
  /var/log/dpkg.log (attached).

  I then tried init=/lib/systemd/systemd in grub without quiet and
  splash and found that it was blocking on "a start job is running for
  Create Volatile files and directories". A search on the internet
  later, I found that the problem was solved by this approach :
  http://forums.debian.net/viewtopic.php?f=10&t=118008

  So, in rescue mode, I did a mv /tmp/ to /fulltmp/ (an ls wouldn't
  return so I'm guessing the /tmp/ is really full and the disk is not
  rocket fast). I recreated /tmp and did a chmod 1777 /tmp, reboot and
  it works!

  While describing this, am not entirelly sure upstart is exempt from
  this bug (how do I check which init was used after I've booted ?)

  This is a very frustrating bug since it doesn't appear on startup even
  when removing quiet or splash.
