That is certainly incorrect.  There should be no 'or' here.

Your version does look correct.

Why do you say that it doesn't?  The 'stopped rc RUNLEVEL=2' event, when
emitted, should trigger this job to be called.  This is the same event that
triggers the start of your tty job, so it certainly is being emitted.

You definitely don't have any of the gdm, lightdm, ubiquity, or oem-config
services installed, correct?

Do you have a /var/log/upstart/plymouth-stop.log on the affected system?  If
so, please attach it.

Please also show the output of 'sudo initctl list | grep plymouth' on this
system.

Title:
  plymouth locks console termios, breaking serial consoles

Status in plymouth package in Ubuntu:
  Incomplete
Status in upstart package in Ubuntu:
  Invalid

Bug description:
  I have a more or less standard non-graphical Ubuntu 14.04 server
  installation.  I boot with console=ttyS1,115200, and I have
  /etc/init/ttyS1.conf that's more or less the same as all the standard
  /etc/init/ttyN.conf files.

  The serial console login doesn't work because plymouth seems to think
  it's showing its bootsplash and it locks the termios settings using
  TIOCSLCKTRMIOS.  This completely breaks /bin/login, which *requires*
  working buffered mode.

  I have no idea what mechanism is supposed to tell Plymouth to dismiss
  its splash screen when boot up is done, but it's clearly broken.  What
  gives?
