Приложение 1. Пример скрипта rc.sysinit
В листинге 11 приведено содержимое файла rc.sysinit с моего компьютера, на котором установлен дистрибутив Mandriva Free 2007 Spring. Поскольку файл этот достаточно большой, листинг разбит на отдельные фрагменты, каждый из которых будет разбираться и комментироваться по отдельности.

Следующие два условных оператора выполняют аналогичные действия с файлами /etc/sysconfig/usb и /etc/sysconfig/system. Заглянув в эти файлы я увидел, что там просто задаются значения нескольких переменных (видимо, они будут использованы где-то в дальнейшем).
Затем, уже безусловно, исполняется файл /etc/init.d/functions. Этот файл содержит определения функций, которые будут использоваться большинством скриптов из каталога /etc/init.
Последний условный оператор в этом фрагменте проверяет, что переменная HOSTNAME задана и имеет ненулевую длину. Если это именно так (то есть HOSTNAME не задана), то этой переменой присваивается значение "localhost".

Если существует файл /etc/sysconfig/init и для него установлено право на чтение, то выполняются записанные в нем команды. А этот файл содержит команды, определяющие некоторые параметры загрузки.
Затем выполняются какие-то действия по подключению Firewire, USB и шифрование диска. Например, проверяется существует ли /proc/bus/usb и является ли он каталогом. Если этот каталог существует, но не указан в файле /proc/mounts, то монтируется файловая система типа usbfs.
