From the mapping that has just done, a new /etc/fstab file will be constructed and you are asked to confirm that the information contained in it is correct:
These are the /etc/fstab entries 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 >
Inspect the partition entries and type "1" or "y" if it is correct, and "2" or "n" if you need to go back and change something.
