In a talk I'd never have imagined would happen, last week at TechEd US, Jeffrey Snover announced DSC for Linux. More information on that is provided on the Windows PowerShell team blog at: http://blogs.msdn.com/b/powershell/archive/2014/05/19/announcing-windows-powershell-desired-state-configuration-for-linux.aspx
While I don't know Linux well enough to provide a detailed comment, the resources shown in that post do not look like the complete set. Nevertheless, this is a great start. I look forward to hearing more and seeing additional resources being added.
