Don't use CCC for lab deployment purposes. Use Disk Utility to create master disk images or use NetRestore
Helper's "Create Master Image" function. NRH will even let you save the master image directly to your file
server.

Rhon,

All the image creation I do takes place on our latest hardware.

Here is a quote from Mike Bombich's site (NetRestore Carbon Copy
Cloner...)

http://www.bombich.com/mactips/asrx-original.html

Prepare the drive on your Master machine

Your master machine should be your latest and greatest machine. Mac OS
X is a very portable operating system, but it is much more portable from newer hardware to older hardware than older to newer. You should
also choose a machine that has the most hardware options/peripherals. For example, if you will have at least one machine with a SuperDrive, use that machine to create your image, even if most other machines won't have that option.

Many people have asked me if you should create a disk image for each
"class" of machine that you intend to support. For example, should you
maintain a separate image for G4s vs. G3s or Desktops vs. Laptops. The
answer is not simple. I typically recommend that you try to maintain
only one master disk image. Create it on your latest and greatest
machine. If that is a desktop machine and the image does not work
quite right on a laptop, then try creating the image on the newest
laptop you have and see if it works OK on the Desktop machine. If it
simply isn't going to work either way, the resort to maintaining
separate images. I suspect that in most cases, though, you will be
able to maintain a single image.

You should consider setting aside an entire drive to the development of your master disk image. Development and testing of an image is much easier if you divide your disk into at least three partitions: one will
be the working (Work) partition, one will be the model (Macintosh) partition and the third will be the testing (Target) partition.


I hope this helps,

David

We are expecting a bunch of 2.5GHz G5 machines for a lab installation,
and we currently have a cluster with several FP iMac machines.

We are in the process of creating a Mac OS 10.3 image to be used on
these systems.

Will I have to create an image for the iMacs as well as another for the
G5's do to the hardware differences? We will be using ASR to image all
of the machines. Having one image makes it easier, but I do not want
the machines to crash every now and then. I am assuming two images is
needed, but I am looking for conformation from someone who has already
tried this.

Thanks in advance,
