The fork-before-open-socket behaviour goes back to the first tag of
plymouth (0.1.0). It has always been that way.

Probably the reason this problem was not noticed earlier is that the
time period between execution of plymouthd and execution of plymouth was
longer. Older hardware was slower, the time to start plymouth would
include the time to load the executable from the CDROM or USB drive.
Even on a VM it would be slower if the VM were on a harddrive. But now
systems are faster, often physical PCs are booted from USB3 drives, or
VMs are on SSD drives, so plymouth gets launched faster, and the race
condition is more likely to be hit.

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).
