文件清理
安装完成后, 清理apt
apt autoremove
apt autoclean
apt clean
最后exit退出
制作 rootfs 镜像文件
# 生成一个适当大小的空镜像，这个大小参考du -h workroot/ -d1
dd if=/dev/zero of=rootfs.img bs=1M count=1024
# 格式化
mkfs.ext4 rootfs.img
# or
mkfs -t ext4 rootfs.img
# 挂载空镜像
mkdir rootfs
sudo mount rootfs.img rootfs/
# 写入文件, 保留权限
sudo cp -rfp workroot/* rootfs/
# 取消挂载
sudo umount rootfs/
# 检查文件系统并自动修复
e2fsck -p -f rootfs.img
# 使镜像紧凑
resize2fs -M rootfs.img
