[Bug 966480] Re: The prompt asking for media removal is not shown at the end of the installation

This is not correct. main.c:main calls ply_create_daemon before
start_boot_server, so the process does fork before binding the port.

When the error occurs the plymouthd log states:

        [main.c] on_display_message:not displaying message Please remove
installation media and close the tray (if any) then press ENTER: as no
splash

Note "not displaying message... as no splash". That error message only
occurs when the splash screen is not being shown. It is not related to
unmounting the filesystem.

Boot and shutdown are different. On boot, plymouth.conf executes
plymouthd, then plymouth-splash.conf executes plymouth show-splash. On
shutdown, plymouth-shutdown.conf executes both plymouthd and plymouth.
Since one script executes both, the timing is tighter.

I have tested the patch and it works.

Bug description:
  *** Edit ***
  This bug affects Ubuntu and other flavours as well and yes, it is alive and doing well with Saucy as well.

  *** End of Edit ***

  At the end of the installation, just after clicking on "Reboot Now" to
  restart the computer, the graphical environment is shut down and the
  TERM signal is sent, asking all processes to terminate. However, the
  prompt asking the user to remove the CD and press Enter is not shown
  (the CD is ejected, then the system hangs).

  Tested on today's (27 March 2012) KUbuntu Precise daily ISO in a VirtualBox VM (using VirtualBox 4.1.8, 1 GiB of RAM, 16 GiB HD, 4 CPUs, EFI disabled).
