The last page of the install instructions prompts the user
to remove the boot media and press return. If the user
booted from a CD-ROM directly, he/she will be unable to
remove the boot media as the CD is not unmounted when the
installation is completed. Instead, the drive door will be
locked until after the machine reboots. (One hopes that the
user will be able to/smart enough to remove the CD while the
machine is in it's BIOS startup process.)

Additionally, the graphical installer also include the
"press enter" when completed statement, where the correct
answer is to push the "Exit" button.
