Public bug reported:

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?
