对！是升级 ISO 镜像，不是升级系统。从旧的镜像升级到新的镜像。可能有点迟了~大家都 Down 好了镜像~我现在才有心情和时间写 Blog 哦~由 Alpha 的 ISO 升到正式版都可以。呃~当然，估计由 Alpha 开始的话，下载量也与直接下载正式版区别不大~这么多人下载，速度当然会慢喇~用 Zsync 来升级镜像减少了下载量也是一个不错的方法哦~

首先要安装 Zsync 喇~

sudo aptitude install zsync

然后，就是把你原有的 ISO 镜像，重命名，无论是 Alpha，Beta，还是 RC，估计 daily-build 也可以哦~都重命名为正式版的名字：

mv ubuntu-9.10-rc-desktop-i386.iso ubuntu-9.10-desktop-i386.iso

(当然，你不用命令行也可) 当然终端的工作目录要 cd 到原镜像所在目录~只要你找到发布镜像的地址，该镜像又有 *.zsync 的就可以了。

命令使用：

zsync *.zsync

(不是运行这个哦~ 这个是使用方法)

然后，你使用以下的命令就可以升级 ISO 镜像了~ Zsync 会自动帮你搞定的~
