If the simple copying of an image leaves you with an unbootable system
What makes you say this? If the systems are identical why can't you just
copy the raw disk from the master system?

What would be useful is a script could be run against an already
configured machine, that created a DVD (or network image) containing all
hardware related RPMS, only the RPMs required for the particular setup,
Then installed a script which went through the hardware phase,
automatically installed the defined RPMs and then generated unique
keys/certificates as the installation CD/DVD does and only prompts for
things like machine name for a configured machine

The YaST AutoInstall system seems to have some of the this kind of
capability but seems to be rather complex to use .... In fact page 2 of
the manual for this answers your question to some extent...

GT,
Thanks for your answer.
I have an SLA with Novell that includes the Zenworks Suite, I'm having a
hard time finding any documentation pertaining to "preparing a SLED10
\SUSE linux image for Cloning".

Spent a lot of time trying to get the Institution I used to work to
(allow me to) test and hopefully deploy Zenworks ... No success *sigh*

Looking at the AutoInstall documentation further it seems that it uses a
XML based script which largely goes through the options described by
other posters in cloning a machine. Real problem is that no mechanism
seems to exist to import an existing package configuration into the
script and support for non-SuSE supported applications and other things
(e.g. Netbeans, Funambol) that deploy either using a bin or jar file is
a bit limited.

The documentation can be found at...

http://www.suse.de/~ug/autoyast_doc/index.html

there is some further work going on but I would suspect Novell may be
moving towards a Zenworks based solution.

For my purposes, I want to establish a base-line configuration that has
some flexibility on hardware configuration, so the next time I have the
kind of messy system collapse I have just had, or I want to move to new
hardware I can quickly get going again. Unfortunately, binary level disk
image cloning is not an option, and even it was does not have any
flexibility (it is rare after a hardware related failure that one is
restoring to the same hardware configuration).

I intend to research this further when I have rebuilt the failed machine.
