The problem is that if file is mounted to a directory via the loopback 
device... the partition that this file and directory reside on cannot be 
unmounted, hence the install wont complete because there   partition 
remains mounted... 

                     

Reproducible: Always
Steps to Reproduce:
	For eg.: 

                                        # 
mkdir /mnt/dos                        # make a directory in /mnt 
                                        # mount -t 
vfat /dev/sda2 /mnt/dos      # mount a dos partition that has the RedHat 
Cd copied to it 

                                        # 
cd /mnt/dos/autoboot                  # switch to a dir within that 
partition                 

                                        # mkdir 
temp                            # mount the initrd.img that is here 
                                        # mv initrd.img initrd.gz 
                                        # gzipd -d initrd.gz 
                                        # mount initrd temp -o loop     
(this operation cause /dev/sda2 to go busy forever.. it will now refuse to 
unmount)

                                        # cd temp               
                                        ... do some stuff in temp ... 
                                        # cd .. 
                                        # umount 
temp                           # unmount and cleanup 
                                        # rm -rf temp 
                                        # 
cd /                                  # get out of mounted dir 
                                        # umount /dev/sda2 
(or /mnt/dos)                (this operation will return an error saying 
that /dev/sda2 is busy...)

        The same problem occurs when you mount a file that is on the cdrom 
during install via loopback and then try to unmount... it makes the cdrom 
busy.. hence the cdrom wont eject at the completion of RedHat      
install.               


Actual Results:  if the file mounted as loopback was on cd.. the cd will 
not eject anymore.. or if it were on a harddisk partition.. that partition 
will not unmount...

Expected Results:  partition/cdrom should eject fine because there should 
not be any thing keeping them busy.
