Preparing and capturing an IHL Image

Note: this step is only necessary if you have prepared an IHL machine that you wish to store as an image for backup or replication purposes

sudo /opt/install/bin/pre-image-clean.py
 * 1) Boot cleanly into IHL
 * 2) Run the IHL pre-image script
 * 1) The script will clean the image of some machine specific identifiers, and shutdown when complete.
 * 2) Do not boot the machine until you are sure it is connected to your imaging server and is configured to PXEboot
 * 3) Take the image as usual (image only one drive, i.e. sda), Clonezilla will use dd instead of partimage because partimage can't handle RAID data, this will take a long time (rates around 25 MB/s are typical)

The process is now complete. Remember when laying down the image that swap space is not imaged, so you will have to tell each new image to use the spare space on the drive for swap as appropriate. RAID will automatically rebuild.
