Mac OS X Server 10.3: Creating an HTTP network install image

Network Image Utility in Mac OS X Server 10.3 can't create an install image for delivery over HTTP, but you can do it using this workaround.
If you must install over HTTP, follow these steps to prepare an image:
  1. Make sure the image is smaller than 2 GB. If necessary, use Disk Utility to compress it.
  2. Use a text editor to open the file NBImageInfo.plist (inside the image's .nbi folder) and change the value of the "Type" key from "NFS" to "HTTP."
  3. Open Server Admin, select NetBoot, click Settings, and check in the General pane to make sure the volume containing the image is enabled for storing images.
  4. In the Image pane, disable and re-enable the image.
  5. Select Web in the Computers & Services list, click Settings, then click Sites.
  6. Double-click the default site that supports NetBoot (Library/WebServer/Documents), click Options, and deselect Performance Cache.
  7. NetInstall the client.
