Do you use cfengine or puppet in your environment? If you install the
base packages via post installation scripts, you can use cfengine to
layer on specific host identities (hostname, IP, configuration,
packages, etc.). With either of these tools you can import
configurations from a running host and then layer them back to a new
host. There is some considerable setup to get it to that point, but
lots of scripts available online so much of the work is done.
