RE: Imaging Software/Hardware for use with Redhat WS Version 3

I agree with Ed 100%, however, I have successfully used Ghost 2003 to
replicate Redhat 7.3 onto many identical Dell boxes.  The only problem
that I ran into was after the restore was done, I had to boot from the
CD in rescue mode, mount / and /boot and reinstall grub (I forget the
command line option I used) but other than that, it did work.

The recommended approach is to build the systems with Kickstart.  That
guarantees that you'll get the right kernel and other packages (e.g.
glibc) for the right architecture over time - for example, if you image
an P4-based system to an Athlon-based system, you probably won't even
boot (I had the same issue with a Ghost image on my Windows desktop at
work - a hyperthreading-enabled image wouldn't boot on my P3).  If a
vendor throws a different Ethernet adapter at you, you'll still work
with a Kickstart'ed system.  If you image and the adapter changes - and
vendors have been known to change Ethernet adapters even within the same
product line - your network may not start.  Ditto with graphics cards.

Kickstarts can be done fairly quickly over the network and can include a
mix of vendor-provided and your own packages.  You have total control
over what the target systems look like.

If you really want to image the systems, you can look at Mondo Rescue -
it can make an exact copy of your system that can then be restored to
another system, even if the disk sizes are different.  However, it won't
do anything about fixing up the hardware inconsistencies, network
addressing, etc.  http://www.mondorescue.org

Setting up a Kickstart-ready environment is a bit of work up front but
it will last you through many more hardware generations than a
disk-image environment will.
