rm -rf / не отрабатывает

Кажется я тут с кем-то обсуждал "неработу" rm -rf / ? Помойму даже в треде про перловый однострочник...

Система: gentoo загруженая с livecd с chroot'ом в рабочую систему (ядро не успел поставить). Ставил xfree, нехватило места на /usr (маленький диск в vmware сделал) во время устанвки. На freenode/#gentoo сказали что это жопа. В общем фтопку это поделие.

Понеслась:

Так что rm -rf / абсолютно всего таки не удаляет...
