我试图在运行在Debian Squeeze上的vserver上安装rsync。
在调用apt-get install rsync之后 ，安装程序停止使用以下输出：
$ apt-get install rsync Reading package lists... Done Building dependency tree Reading state information...

但我无法弄清楚问题所在！
由于/ etc / default / halt被符号链接到/ bin / true，所以发生错误。
这在早期版本中是可行的。 但是直到Debian 6 InitScripts在脚本文件的头文件中查找依赖关系。 由于暂停符号链接到一个值InitScripts无法parsing结果并导致错误。
用原始内容replace/ etc / default / halt解决了这个问题。
