在Ubuntu中使用lsb-base-logging脚本和“INITOUTPUT”variables

我有一些麻烦在Ubuntu机器上安装Mysql服务器。 经过一番search之后，我发现Mysql的初始化脚本（/etc/init.d/mysql）会尝试调用“/etc/lsb-base-logging.sh”shell脚本，它的四行代码检查variables的值“INITOUTPUT”，这个variables没有定义。

我刚刚评论这4条线，一切正常。 我检查了使用Fedora 10的笔记本电脑，而且根本没有“lsb-base-logging.sh”脚本。 有人知道这个脚本在系统中做了什么特定的任务，为什么它使用一个没有定义的variables？ 这个variables实际上是什么？

更新我在这里附上脚本。 文件：/etc/lsb-base-logging.sh
