From the mapping you have just done, the computers /etc/fstab file will be constructed and you are asked to confirm that the information contained in it is correct:
These are the filesystems that will be created:
/dev/hda1 /boot ext3
/dev/hda2 none swap
/dev/hda3 / xfs
Are you satisfied with the above configuration?
=> 1. yes
2. no
[yes] >
Inspect the fstab entries and type "2" or "n" if you need to go back and change something, or "1" or "y" to move on to the "Build New File System" screen.
