You shouldn't use the project_build_arm/*/root directory to boot from
NFS. The /dev entries are normal files as we don't want to require
root rights while building. Instead create a tarball (target
filesystem options->tar the root filesystem) and extract that (found
under binaries/) as root on your nfs server.
