Судя по репам у Вас RFRemix29. После обновления что будет? Репов то для RFRemix30 нет. Будет чистая Fedora?

Сейчас RFRemix29. Речь шла об очередном (текущем) обновлении.
До 30 обновляться не буду. Пропущу. Команда взяла отпуск на один релиз. Обновлюсь до RFRemix31 месяца через три после его выхода.
