Debian
安裝 syslog-ng
我在 Debian Squeeze 上有一個帶有 nagios、cacti 和 nedi 的監控伺服器。當我嘗試通過 apt-get 安裝 syslog-ng 時，出現如下錯誤。我認為 rc 中的符號連結有問題。但我不知道如何解決這個問題。

那些 LSB 標記失去的警告，這意味著在服務腳本 /etc/init.d/service_name 中缺少如下內容：
### BEGIN INIT INFO # Provides: scriptname # Required-Start: $remote_fs $syslog # Required-Stop: $remote_fs $syslog # Default-Start: 2 3 4 5 # Default-Stop: 0 1 6 # Short-Description: Start daemon at boot time # Description: Enable service provided by daemon. ### END INIT INFO簡單的解決方法是刪除 insserv（在 Debian 6.0 中替換了 update-rc.d）：
apt-get remove insserv或者可能更好的解決方案是在所有需要的腳本中添加那些缺失的標籤。
以下是 debian wiki 上 LSB 標記的詳細描述： LSBInitScripts
在此頁面上很好地描述了什麼是 LSB： 基於 LSB 初始化標準的初始化腳本
