V. Приложения

D. Скрипты загрузки и sysconfig версии-20240825

Скрипты в этом приложении перечислены по каталогу, в котором они обычно находятся. Порядок /etc/rc.d/init.d, /etc/sysconfig, /etc/sysconfig/network-devices, и /etc/sysconfig/network-devices/services. В каждом разделе файлы перечислены в порядке их обычного вызова.

D.1. /etc/rc.d/init.d/rc

Скрипт rc является первым скриптом, вызываемым init и инициирующим процесс загрузки.

# Notes       : Updates March 24th, 2022: new semantics of S/K files
#               - Instead of testing that S scripts were K scripts in the
#                 previous runlevel, test that they were not S scripts
#               - Instead of testing that K scripts were S scripts in the
#                 previous runlevel, test that they were not K scripts
#               - S scripts in runlevel 0 or 6 are now run with
#                "script start" (was "script stop" previously).
