dbus-daemon необходим для сервера?
У меня есть сервер CentOS 7, который я только через ssh (т.е. не требуется графический интерфейс).
Интересно в таком случае dbus-daemon все равно должен быть запущен как согласно вики, похоже, что это только для рабочего стола.
Я пытаюсь отключить все ненужные сервисы / процессы на моем сервере, чтобы уменьшить потерю кэша и оптимизировать время ожидания:
