Проблема такая:
Кфс лежит в виде образа jffs на флэшке. Флешку на париции разбил через параметр юбута. Ядро стартует и монтирует jffs.
Далее передается упраление на initab который у меня сотоит из одной строки:
echo -e -n "\n\n--\nStart init\n" >&2
И после почемуто происходит самостирание имиджа кфс. Т.е. при следующей загрузке ядро уже не видит его. Че не так делаю? подскажите плз.
