[РЕШЕНО]FlashStick и Gentoo[ЧАСТИЧНО]

Вообщем как всегда... По этому документу http://en.gentoo-wiki.com/wiki/Initramfs научился создавать свой образ ramfs. Взял за основу проблемный образ. Всё что нужно это правильно подправить init-скрипт(пробовал изменять - работает). Вот этот скрипт: http://pastebin.com/m1a0a37d8
Наивно конечно с моей стороны, но всё же эта секция # Determine root device
отвечает за root device. Где-то там проблема...

#Спустя какое-то время(минут15)

В том скрипте sleep 15 добавил я. Это решает проблему. Конечно надо его уменьшить до необходимого,нужного и желаемого времени. Но всё же хотелось бы решить проблему иным путём. Хотя тот факт что ядро ещё не загрузило необходимый код иным путём может решить и нельзя.
PS::.. Напишите хоть кто-то что-нибудь, а то я сомневаюсь что кто-то читает.

Выкладываю здесь содержимое init-скрипта(остальные инструкции можно получить прочитав топик):

НИКТО НИКОГДА НЕ ОСТАВЛЯЙТЕ РЕШЕННЫЕ ПРОБЛЕМЫ БЕЗ ПРИМЕРОВ ИЛИ ОТВЕТОВ(как сделал один товарищ). И даже намерения типа : "Предлагаю создать статью на вики по этой проблеме всем дружно" или "Могу прикрепить если надо" не устоят перед зыбким песком времени =). Когда кому-то будет надо - будет просто поздно уже и т.д.

Копания в пакетах Acrh'a, установка "eдва живого" mkinitcpio ни к чему не привели. Эх, если б как-нибудь udev засунуть в initramfs - проблема была б решена.
