"System V method of initialization is one of the most widely used across most Linux distributions. It definitely eases the system administrators job. There's a lot more than autoexec.bat and config.sys here. We've written this article for novice users. It explains the concept of runlevels, initialization scripts and the significance of /etc/rc.d."
"In the traditional BSD style of startup, there are only a few initialization scripts, which are something like the autoexec.bat and config.sys pair of DOS. Commands are executed and services are loaded up sequentially as given in the scripts."
"But the system administrator may want a more flexible and convenient way of managing the system. There will be times when certain services are not required. The BSD style of startup as adopted by distributions like Slackware offered only a few system states at the disposal of the administrator. A single user state was provided for maintenance and there was a normal multi-user state."
