    <para>
      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, xfs, jfs).

      <title>KA method</title>
      <para>
	With KA method you can quickly duplicate a node using a <emphasis role="bold">desc</emphasis>
	file describing partitions. KA method only duplicate data on partitions, so if you have 80go HDD disk, and
	only 10go on it, KA only duplicates 10go, and not the whole disk. KA method doesn't not support RAID software.

	  Mandriva Linux installer supports various methods to install a computer. With PXE configuration file you can specify wich method you want to use to install your node, or add a specific option at boot prompt. Edit your default PXE configuration file to add your custom entry (<emphasis role="bold">/var/lib/tftpboot/X86PC/linux/pxelinux.cfg/default</emphasis>).

      <title>Stage2, the duplication process</title>
      <para>
	Once all the nodes have found the <emphasis role="bold">KA</emphasis> server, the first

	<emphasis role="bold">rescue_stage2</emphasis> from the <emphasis role="bold">/mnt/ka</emphasis> directory
	of the golden node, in the client's nodes memory (<emphasis role="bold">/dev/ram3</emphasis>). Then, nodes chroot their
	memories (the <emphasis role="bold">/tmp/stage2</emphasis> directory), and launch the <emphasis role="bold">drvinst</emphasis> command from the rescue disk, to probe all needed their modules (drivers).
	Then, the second step of the duplication starts.
      </para>
      <para>
	The duplication process will clone your drives following
	the description you have made (<emphasis role="bold">/tmp/desc</emphasis> of the golden node).
	Nodes will rewrite their partition table, then format their filesystems (ReiserFs, XFS,
	ext2/3, JFS). All new partitions will be mounted in the <emphasis role="bold">/mnt/disk</emphasis> directory.
	Then, the drive duplication process will begin. On a fast Ethernet switch you can reach speeds of 10MBytes/sec.

	At the end of the duplication process, each node will
	chroot its partitions and rebuild its <emphasis role="bold">/boot/initrd.img</emphasis>,
	and <emphasis role="bold">/etc/modprobe.conf</emphasis> files.
	This step ensures that your node will reboot using its potential
	SCSI drives and adjusting its network card driver. Before
	rebooting, each node reinstalls lilo/grub. All your node are
	now ready, and are clone of master node.
