Problems with SCCM 2012 OSD and unattend.xml

Hello,

I am trying to duplicate a Task Sequence in SCCM 2012 OSD that we have had working in SCCM 2007 for a couple years now.  With 2007 OSD, we did some copying of files/executables to a c:\sources folder and at the end of the TS, we had some "first logon commands" on oobeSystem pass in the unattended.xml file that ran.  

Now with SCCM 2012, it seems to be running the unattended.xml file right after the first Setup Windows and Configuration Manager step and before we are able to copy the files to the c:\sources folder. 

FYI, the first logon commands are set to run at Pass 7 oobeSystem.

Anyone have any insight into this?

Thanks
