The RSP partition not only includes the RSP images, packages and VMs, it also includes the VMware Server software. So since you have no packages or VMs, it would be RSP image and VMware software.
When I install the RSP the free disk space are showed "6.6 GB used / 62.8 GB free / 69.4 GB total ". After delete all default packages, the free space are showed "4.4 GB used / 65.0 GB free / 69.4 GB total". What are using 4.4 GB?
