The reason is that the rootfs-lsb-sdk does not contain the package
nfs-utils. The receipe nfs-util generates the package nfs-utils-client,
that contains mount.nfs. You can see from strace that mount tries to
exec mount.nfs, that is not installed.

Since ELDK is derived from Yocto, there is no reposity with binary
packages, nbut you can easy compile ELDK yourself. Check at:

Even in this case, the libpam libraries are not part of the generated
root filesystem. You have to build these libraries yourself.
