How does on build an image for and what tools does one need to clone a

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?

I think this really depends on whether one wants to clone a
configuration in which some settings are unique to the workstation i.e.
certificates, I.D.s, keys, hardware drivers etc but the installed
application base is the same, or just make a mirror image.
This is a common problem in the Education sector where one needs to a
lot of machines with apparently the same set of applications. The former
does make this installation relatively straightforward, the latter could
give major headaches if you need to put the same image on multiple
machines, and would not be entirely useful when hardware components had
changed
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...
Ghost used to do this with Windows, but I do not think the consumer
version does this anymore. The only other tools I have come across which
could do this are commercial (Ultris, Zen and something from M$).
