准备工作：
具体步骤：
开发板进入 recovery 模式
sudo reboot recovery
将u盘挂载到 udisk 目录
mount /path/to/SDCARD /udisk
使用 dd 命令备份出来根文件系统
#如有需要，这些路径可以排除（根据需要自己选择）
/dev/*,/proc/*,/sys/*,/tmp/*,/run/*,/mnt/*,/media/*,/lost+found,/boot
root@rk3588:/# dd if=/dev/mmcblk0p6 of=/udisk/youyeetoo-rootfs.img
29360128+0 records in
29360128+0 records out
进入 /udisk 目录检查镜像并瘦身
root@rk3588:/udisk# e2fsck -f youyeetoo-rootfs.img
e2fsck 1.46.5 (30-Dec-2021)
Pass 1: Checking inodes, blocks, and sizes
Pass 2: Checking directory structure
Pass 3: Checking directory connectivity
Pass 4: Checking reference counts
Pass 5: Checking group summary information
youyeetoo-rootfs.img: 73422/904960 files (0.3% non-contiguous),
889075/3670016 blocks
root@rk3588:/udisk# resize2fs -M youyeetoo-rootfs.img
resize2fs 1.46.5 (30-Dec-2021)
Resizing the filesystem on youyeetoo-rootfs.img to 1046578 (4k) blocks.
The filesystem on youyeetoo-rootfs.img is now 1046578 (4k) blocks long.
同步之后得到根文件系统如下
root@rk3588:/udisk# sync
root@rk3588:/udisk# ls -lh
total 4G
-rw-r--r-- 1 root root 4.0G Dec 22 16:00 youyeetoo-rootfs.img
备份出来的根文件系统可以再次和其他分区二次打包成为完整镜像进行批量部署。
针对部分客户需要保留当前板级配置信息，请按照如下流程操作
sudo apt-get install lib32stdc++6
tar -xzf yytRepack.tar.gz

打包之前将已经配置好环境的根文件系统从开发板备份出来替换掉 output 目录中的 rootfs.img
cd path/to/yytRepack
cp <sourceDir>/BAK_roots.img ./output/Image/rootfs.img
./pack.sh
打包之后目录如下
$ ls
bin output pack.sh unpack.sh
$ ./pack.sh
