将opkg.conf修改成（sda1这个对应自己硬盘目录）
src/gz packages http://downloads.openwrt.org/backfire/10.03.1-rc4/brcm63xx/packages/
dest root /
dest usb /mnt/sda1/opt
dest ram /mnt/sda1/tmp
lists_dir ext /var/opkg-lists
option overlay_root /mnt/sda1/overlay
安装软件要在命令行下安装
如：opkg -d usb install proftpd
修改profile文件
vi /etc/profile
export PATH=/bin:/sbin:/usr/bin:/usr/sbin:/mnt/sda1/opt/sbin:/mnt/sda1/opt/usr/bin
export LD_LIBRARY_PATH=/lib:/usr/lib:/mnt/sda1/opt/lib:/mnt/sda1/opt/usr/lib
然后就需要opkg-link这个工具
具体代码如下

将opkg-link复制到/下
执行chmod +x /opkg-link
opkg说明
/opkg-link add mini-httpd 连接mini-httpd到系统目录
/opkg-link remove mini-httpd 删除根目录的mini-httpd连接
/opkg-link mount /mnt/sda1/opt 把 /mnt/hda1/opt下所有的软件连接到系统目录
/opkg-link umount /mnt/sda1/opt 删除对/mnt/hda1/opt下所有的连接
连接之后如往硬盘安装软件装完后再运行下连接命令
