Step 12Build A NetBoot Image From A Bootable Volume...
In this example we're going to build a NetBoot image from a bootable drive.
The first step is to build a bootable drive! I don't recommend using your regular boot drive. Instead, install OS X on another drive or partition. I'm not going to give you a step-by-step about how to do this. Suffice it to say; Click the Custom button before the final Install button to deselect any parts you don't need.
Set the primary user to Administrator (short name admin and set a password) and create a non-administrative account called Guest without a password. You can make the later the auto-login account if you want. How you setup this boot drive is entirely up to you. These are just pointers to make it more generic.
Run all the updates and install whatever programs you want the user's to have available. Remember that once this is converted to a NetBoot image, it will come up the same way you last left it.
Boot back to your regular drive and log into the Root account.
Launch System Image Utility and click the New Boot icon (picture 1). Give it a simple name and a unique index number below 4096. In the description put the details to remind yourself why you made this image. Again, leave NFS and Local selected.
Select the Contents tab and select your bootable drive in the Image Source popup menu (picture 2).
Note that if you built this bootable drive using the Install disks from an Intel Mac, the resulting image will be a Universal image (will boot both Intel and PPC). This will also be the case with OS X 10.5 (Leopard) images. Otherwise, the image will be PPC only.
Go ahead and click the Create button to build the image (pictures 3 & 4).
All you need to do now open the NBImageInfo.plist file with Property List Editor, correct the Architectures settings as in step 10, remove the EnabledSystemIdentifiers and DisabledSystemIdentifiers and set isEnabled item to true (picture 5).
Note that you may also set IsDefault to true to make this default image. Only one image should be set to default for each platform.

If you've got an Intel Mac, any bootable drive must use the GUID structure. Likewise, a PPC Mac must use Apple Partition Map.
