Система отличненько работает с sys-apps/portage-2.2.2, но ругается так при попытке обновить оной до 2.3-r3 или 2.3-r4. Стабильные версии. Не пойму, что у меня не так. Однажды уже спрашивал, но решил тогда откатиться. Теперь то же и со следующей версией портежа... Гугл молчит.
Если это какая-то особая нелюбовь портежа и моей системы -- возможно ли безболезненно funtoo перевести на paludis, пробовал ли кто? Спасибо.

Повторюсь -- с предыдущей версией ВСЁ РАБОТАЛО. Что именно не так нужно обновить, не могу понять... Ещё раз спасибо.

UPD: Начинает адекватно работать, если убрать ВСЕ оверлеи, кроме основного дерева.
Только остаётся:

!!! Repository name or alias 'gentoo', defined for repository 'gentoo', overrides existing alias or repository.
!!! Location not set for repository funtoo

Но это совсем не решение. Возможно, их иначе сейчас следует подключать?
