> When using initramfs, it is useless to put an initrd in the iso image.
> This patch makes the image to only contain the kernel image, and
> also removes the initrd line from menu.lst

We prefer positive logic, ie.:

ifeq ($(BR2_TARGET_ROOTFS_INITRAMFS),y)
    sed blabla
else
    cp rootfs.cpio blabla
endif
