我在 Debian Squeeze 上有一个带有 nagios、cacti 和 nedi 的监控服务器。当我尝试通过 apt-get 安装 syslog-ng 时，出现下面的错误。我认为 rc 中的符号链接有问题。但我不知道如何解决这个问题。

这些警告表明 LSB 标签缺失，这意味着服务脚本 /etc/init.d/service_name 中缺少如下内容：
### 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
简单的解决方法是删除 insserv（在 Debian 6.0 中取代了 update-rc.d）：
apt-get remove insserv
或者可能更好的解决方案是在所有需要的脚本中添加那些缺失的标签。
以下是 Debian wiki 上关于 LSB 标签的详细描述：
LSBInitScripts
此页很好地描述了什么是 LSB：
