Как видите, всё взлетело нормально. :( Чего ему не хватает для нормального старта? Ладно - первый раз, возможно, ещё не поднялся бридж, но второй-то раз он стартует точно после поднятия интерфейса... И ещё одно - первые 6 строк в логе при старте dhcpd пишутся нормально, а потом (начиная с " WARNING: Host declarations are global." - все строки в логе, касающиеся dhcpd тупо дублируются. :( Кто-нибудь с таким сталкивался?
