make menuconfig

  | |(128) Kernel partition size (in MB)| |  
  | |(1024) Root filesystem partition size (in MB)| |
在config配置文件中对应修改： 
CONFIG_TARGET_KERNEL_PARTSIZE=128
CONFIG_TARGET_ROOTFS_PARTSIZE=1024

				当学会了搭建openwrt编译环境，肯定是想编译有一些自己想要的东西固件，要知道官方给的固件是很简洁的，不仅没有web界面(Luci-web)，连无线默认都不是开启的，这也太不像个无线路由器的样子了。
我们会使用make kernelconfig和make menuconfig这种方法来自定义软件包，不过，这样编译出来的固件仍然不具个性化，因为，无线仍然没有开启，像SSID、路由主机名、默认
				主机为 ubuntu 14 x64 硬件： 优酷土豆宝 cpuMT7620A，内存128M，flash 32M
有2个源，用哪个也可以
git clone https://github.com/openwrt/openwrt.git
git clone https://git.openwrt.org/openwrt/openwrt.git
安装的插件
gcc, binutils, bzip2, flex, python, perl, make, find, grep, diff,
unzip, gawk,
				最近在研究Openwrt，有的时候因为批量配置方便需要，想把一个设置好的路由器的Firmware备份下来。不过恢复到同型号的另一个路由器上会出现路由器配置页面里网络-无线里面变成两个无线网卡的现象，我研究了一段时间，发现大家的解决方案都是重新编译固件。不过我现在手头的电脑比较老旧，开不了虚拟机，无法重新编译。
首先查看分区
