Peter,
If believe "cp -rL" is what you're looking for, for the symlink issue. The -L option: "always follow symbolic links in SOURCE". The platform specific getting starting guides tell you to use cp -rL when copying the opencpi directory within the sdcard directory. For example the ZedBoard Getting Starting Guide says for xilinx13_3 run:
cp -rL /opt/opencpi/cdk/zed/sdcard-xilinx13_3/opencpi run/media/<user>/<partition>/
Regards,
Jerry

I have certainly had problems with symlinks when mounting a "host" file
system into a VM. I solve it by always using NFS, even between a VM and
its host.
I'm not sure that is your issue...
Yes, that is the intention of that directory.
I'm actually doing something similar later today to test some new FPGA
loading code...
