The rbfkernelup.py yum plugin in RBF is meant for this purpose. For the Cubietruck, it will add an entry to /boot/extlinux/extlinux.conf. You can read more about it in the section "Usage of yumplugins/rbfkernelup.py" in the README https://github.com/mndar/rbf/blob/master/README.md and in https://github.com/mndar/rbf/blob/master/doc/KERNELUP_README.md Regards Mandar Joshi
