what do i install on my CM2012 R2 site?

Seems to be some confusion among folks on which SP2/R2SP1 download you should run on your CM2012 R2 site.  Here is the important part from the notes:  If you have a System Center 2012 R2 Configuration Manager installation, you can use the System Center 2012 Configuration Manager SP2 media to install the latest patches and automatically upgrade to System Center 2012 R2 Configuration Manager SP1.   The SP2 media is the 700MB+ file you downloaded.  If you are doing a new install, install SP2 and then R2 SP1.
