Title:
  init 1 locks you out of system immediately when run from virtual
  console

Status in systemd package in Ubuntu:
  New

Bug description:
  I don't think it's just me, as I'm able to reproduce this on 2
  physical systems as well as a vanilla qemu/kvm instance, immediately
  after fresh installs from both ubuntu-16.04.1-desktop-amd64.iso and
  ubuntu-16.04.2-desktop-amd64.iso

  
  When I run 'sudo init 1' or 'sudo telinit 1' from any virtual console, the system never gets to single-user mode. Instead, I am presented with a non-functioning login prompt and no way to actually interact with the machine except Ctrl-Alt-Del, which luckily still works.

  The login prompts look normal, but only appear on two virtual
  consoles: tty1 always, plus the one I was using (if it wasn't tty1).
  All others are blank. Typing my username results in the message
  "System is going down," instead of a password prompt. After a couple
  of minutes, it will clear the screen and draw a fresh prompt, with the
  same results; otherwise, nothing changes until I give the three-
  fingered salute to reboot. I've attached a screenshot from the VM.

  This happens regardless of whether I first log out of my desktop, stop
  the lightdm service entirely, or neither. The truly bizarre part is
  that if I enter the command from inside a gnome-terminal running on
  the desktop, it works as expected. It's a little unbelievable, but
  seems to be reliably reproduceable.
