Hi Nico,
I was able to get my ramdisk booting, the main problem in my view was
the RPATH was being set for runtime compiling and i believe the system
was looking for the RPATH not RPATH+ /lib + /usr/lib in the search
path when it was booting.
So what i changed was not to create RPATH but adding rpath-link which
looks where the library's are during link time not runtime like RPATH.
Well happy that is working and here is my path for wapper.sh which is
located in target/toolchain/files.
