/etc/rc.d/rc.local似乎是很多linux系统管理员的偏爱，因为凡是需要随系统自动启动的服务、程序等，只要系统没有提供Sys V风格的启动脚本，就把这些需求都塞到/etc/rc.d/rc.local。
当然，绝大部分情况下，你会发现这一切都工作得很正常，看上去也很美好。不过，当你遇到了一些诡异的问题的时候，也许你应该好好的去看看/etc/rc.d/rc.local里都写了什么了？
虽然/etc/rc.d/rc.local 的描述是你可以把你需要的自动启动的程序放到这里，不过那仅仅只是限于没有别的地方可以放置了，或者说系统也没有提供其他办法了，我们才这么干，然而实际 上，我碰到的很多/etc/rc.d/rc.local里放置的内容，其实系统提供了更好的处理方式
