At the end of the graphical install, a screen appears instructing the user to eject all floppy disks and cd's used during the installation and then press enter to reboot. Ejecting the cd-rom is not physically possible, presumably because it has yet to be unmounted. After pressing enter, the machine proceded to do the normal post install sequence of unmounting the file system and automatically ejecting the cd-rom. Since it is not possible to eject the cd-rom and since the normal reboot sequence does it automatically, this prompt should not appear at the end of the install.
fixed in CVS.
