NetBoot issues 10.8.x server

Issues may be encountered when NetBooting a device on OS X 10.8.x server where Casper Imaging will crash or the ability to erase or re-image 'Macintosh HD' will fail. This is due to the NetBoot image net being fully 'disk less'. A way to check is to launch Disk Utility and verify the mount point of is not /var/private/netboot

To resolve this issue:

  1. Convert the NetBoot.nbi image to read/write
  2. Edit /Volumes/{VolumeName}/etc/rc.netboot, line:
    NETBOOT_SHADOW=${NETBOOT_SHADOW:-NETWORK-}
    to read
    NETBOOT_SHADOW=${NETBOOT_SHADOW:=-NETWORK-}
  3. Convert the image back to read-only compressed.
  4. Restart the NetInstall Service.
