I'm using Puppet as a configuration management tool in the open source Collabograte project that I recently announced:
http://kartiksubbarao.com/announcing-collabograteCurrently, the puppet manifests enable integration points among the following software packages: Cyrus IMAP,
ejabberd, INN, MediaWiki, OpenLDAP,
Postfix, Sympa, WordPress
I'd be very interested in hearing any comments, ideas, suggestions, or questions you might have on this. I want to help Enterprise IT do a better job of integrating open source into their environments, as well as improve the collaboration between Enterprise IT and open source project communities.
Please feel free to respond here, on the Collabograte mailing list, or email me directly, whichever you prefer.
Thanks,
-Kartik
