mount /dev/sda1 /mnt
mkdir /tmp/root
mount -o bind / /tmp/root
cp /tmp/root/* /mnt -a

mkdir -p /tmp/cproot
mount --bind / /tmp/cproot
tar -C /tmp/cproot -cvf - . | tar -C /mnt/sda1 -xf -
umount /tmp/cproot

点SYSTEM下的STARTUP,启动 fstab usb
再回到SYSTEM下的MOUNT POINTS,修改挂载点，点击开启挂载mount, 选中对于block-extroot则设置挂载到overlay存储

uci show mjpg-streamer

用fswebcam测试camera

fswebcam --device /dev/video0 output.jpeg --verbose

对于输出yuv格式的camera

mjpg_streamer -i "input_uvc.so -r 320x240 -f 15 -yuv" -o "output_http.so -p 8080 -w /www"

openwrt备份命令：

查看：cat /proc/mtd

备份：dd if=/dev/mtd4 of=/tmp/art.bin

然后用winscp软件在/tmp/ 目录下，复制下来！

openwrt恢复命令：
先将固件用winscp软件上传到/tmp/ 目录下
然后输入（请见9楼）
mtd -r write /tmp/art.bin art

Normally opkg installs packages from a repository which is specified in /etc/opkg.conf:

src/gz packages http://downloads.openwrt.org/backfire/10.03/brcm63xx/packages
dest root /
dest ram /tmp
lists_dir ext /var/opkg-lists
option overlay_root /overlay

What if you built a package locally and want to install that instead? Do this instead of setting up your own web server:

Copy your package (.ipk file) to /tmp on the router:

$ scp mypackage_brcm63xx.ipk root@172.30.33.1:/tmp/

Copy the Packages file to the router:

$ scp Packages root@172.30.33.1:/var/opkg-lists/packages

Log on the router, cd /tmp and install the local package:
```
root@OpenWrt:~# opkg install mypackage_brcm63xx.ipk
```
