puppet, chef, etc

I've seen various reports of people using tools like puppet and chef for deploying systems. I'm looking at setting up some scripts to create test images for Debian. The main use will be for testing SE Linux so I can test all the combinations of daemons that the policy should support. But I also plan to publish them for the benefit of other people. What system do you recommend for creating such images? Puppet? Chef? Something else? -- My Main Blog http://etbe.coker.com.au/ My Documents Blog http://doc.coker.com.au/
