[devel] Master 2.4 LVM an RAID startup

Добрый день.

Захотелось мне LVM поверх MD

Сначала был модифицирован /etc/rc.d/rc.sysinit следующим 
способом.
1. Сперва активируем MD.
2. Затем активируем LVM.
3. Затем активируем swap.

Потом был модифицирован /etc/init.d/halt следующим образом.
1. Затем отключаем swap.
2. Отключаем LVM.
3. Отключаем MD.

Я понимаю что хак, но может быть это сделать правильно и затем 
выпустить update на startup?

Патч прилагается. Хотел сперва в глюкозавра, да не нашел как в 
нем аттачи прицеплять.
