PXE rescue NFS and kickstart.cfg

I'm trying to setup a PXE bootable rescue setup that loads it's requirements from NFS. To not have to specify the NFS server info include path to installation media I'm using a kickstart.cfg file. This all works great except it doesn't ask if I want it to find my filesystem and mount it, I do not want it to mount it as part of what I want to accomplish here is resizing filesystems. Anyone know of a flag/option to either force rescue NOT to find and mount an existing installation or prompt the user??

Thanks, Mike

Here is the contents of the kickstart.cfg file:

#System keyboard
