Goal of duplication is to easily deploy a computer over network without taking care of numbers of computer. In this documentation, we call golden node the node we want to clone.
We can duplicate SCSI or IDE hard drive, and duplication support multiple filesystem (reiserfs, ext2, ext3, ext4, xfs, jfs).

only 10go on it, KA only duplicates 10go, and not the whole disk. KA method doesn't not support RAID software.
