SharePoint 2010 with Opalis 6.3
One of my SharePoint colleagues send me this today which is quite interesting:
http://blogs.msdn.com/b/emberger/archive/2010/11/23/opalis-6-3-to-orchestrate-sharepoint-2010.aspx
The guy is explaining how you can use Opalis to install all the SharePoint 2010 Prerequisites from a DSL (Definitive Software Library - ITIL standards) to get them in the SharePointOS.

Nice Job!
