tak, restart postfix'a, restart vservera ale dalej bez zmian

tak wygląda strace procesu master dla chrootowanego procesu smtpd (na 
pierwszy rzut oka wygląda tak samo gdy smtpd nie jest chrootowany a 
przynajmniej część z otwieraniem /etc/resolv.conf)

jak w powyższym zobaczyłem otwierany socket procesu nscd to pomyślałem, 
że to coś psuje ale niestety, restart nscd również nie pomaga,
co jeszcze może być nie tak?
