# 因为是在WSL2上交叉制作所以需要，启动服务binfmt-support可解决：chroot: failed to run command '/bin/bash': Exec format error
sudo apt install binfmt-support qemu-user-static debootstrap

# 开始获取根文件系统
sudo qemu-debootstrap --arch=arm64 stable ${ROOT_PATH}/ http://mirrors.ustc.edu.cn/debian/

# 挂载ARM64的根文件系统
sudo mount -t proc /proc ${ROOT_PATH}/proc
sudo mount -t sysfs /sys ${ROOT_PATH}/sys
sudo mount -o bind /dev ${ROOT_PATH}/dev

# 切换根目录后可以执行你想要做的操作

# 卸载ARM64的根文件系统
