    Check kernel usr/initramfs_list,

    Try remove old rootfs and rebuild kernel. 

    rm -rf ~/rootfs
cp -a ~/buildroot/build_nios2/root ~/rootfs
cd ~/rootfs#  remove include and lib to save space#  the dev nodes are generated via ~/download/rootfs_list
rm -rf dev usr/include usr/lib#  you may use this instead of the one from buildroot
cp ~/download/inittab etc#  check rootfs size
du ~/rootfs

    I do it follow hippo's advice.

    It seems resultful. But I will still test more.
