-   for network boot for now, we may provide our own NFS implementation in
-   a later version. That means that we allocate a huge block of memory for
-   the entire file before loading it. We use the location where the kernel puts
-   RTAS, it's not used by the bootloader and if freed when the kernel is booted.
-   This will have to be changed if we plan to instanciate RTAS in the bootloader
-   itself
