[SOLVED] emerge --depclean предлагает удалить системные пакеты

Обновил порты

emerge --sync
emerge -uDNav world
emerge -uDNav system
revdep-rebuild -i

После этого решил удалить ненужные пакеты

emerge -avc

В итоге получил примерно такой список

>>> These are the packages that would be unmerged:

Решил проверить действительно ли nano нет в system.

emerge -pv system | grep nano

Пакета nano в system не оказалось. Отсюда возник вопрос - данный пакет реально убрали из system или я где-то накосячил?
