zsync镜像更新

假设目前已有镜像文件trusty-desktop-amd64.iso，要更新到ubuntu-14.04-desktop-i386.iso

sudo apt-get install zsync
zsync -i trusty-desktop-amd64.iso http://mirrors.ustc.edu.cn/ubuntu-releases/14.04/ubuntu-14.04-desktop-i386.iso.zsync

Read trusty-desktop-amd64.iso. Target 35.3% complete. 实验证明这都能省下1/3的流量]

最好更新后进行镜像的md5校验md5sum ubuntu-14.04-desktop-i386.iso
