D. Загрузочные и конфигурационные скрипты версии 20100627
Скрипты, приведенные в этом приложении, перечисляются в соответствии с тем, как они обычно размещены в директориях. Прядок следующий: /etc/rc.d/init.d, /etc/sysconfig, /etc/sysconfig/network-devices и /etc/sysconfig/network-devices/services. Внутри каждого раздела, файлы перечислены в том порядке, в котором они обычно вызываются.
D.1. /etc/rc.d/init.d/rc
Скрипт rc является первым скриптом, который вызывается из init и инициирует процедуру загрузки.
