Microsoft has just released the following download for ConfigMgr 2012:
Microsoft System Center 2012 Service Pack 1 Beta Configuration Manager – Clients for Additional Operating Systems
Microsoft System Center 2012 Configuration Manager SP1 Beta supports the management of Linux and UNIX servers. The clients for Linux and UNIX extends the scope of your Configuration Manager environment to collect inventory, deploy software, and run reports about Linux and UNIX servers in your enterprise. The client operates as a workgroup client that is managed by Configuration Manager. I’ve updated the Microsoft Downloads page accordingly.
