安裝 rsync 在子程序中停止並出現錯誤
我嘗試在執行在 Debian Squeeze 上的虛擬伺服器上安裝 rsync。
呼叫apt-get install rsync後，安裝程序停止使用以下輸出：
$ apt-get install rsync Reading package lists... Done Building dependency tree Reading state information...

但我無法弄清楚問題所在！
發生錯誤是因為 /etc/default/halt 符號連結到 /bin/true。
這在早期版本中是可能的。但直到 Debian 6 InitScripts 在腳本文件的標頭檔中查找依賴項。因為 halt 符號連結到一個值 InitScripts 無法解析結果並導致錯誤。
將 /etc/default/halt 替換為其原始內容解決了該問題。
