To do this, we reboot our target machine using the *Linux System Rescue CD*.
This CD has all the tools on it we need to do both image creation and
restoration. You can find the iso image for this disk here::

You will also need access to a place to store and retrieve your images.
we need to image is the *operating system itself*. In this example, we know
there are 2 partitions of interest:
 
``sda1`` - The ``/boot`` partition
 
``sda2`` - The rest of the operating system, in this case contained in LVM containers
 
The idea is that if the machine were to go dead, a disk failed, or what have you, this

disk. This makes it easy to lay your operating system down on a new,
larger disk. Do an image of the old disk, restore it to the new disk,
