We currently use a LOG_EMERG log mask to represent the fact that we don't know yet what the mask resulting from configuration should be, before the command line is parsed. However, we have the necessity of representing another phase as well, that is, configuration is parsed but we didn't daemonise yet, or we're not ready for operation yet. The next patch will add that notion explicitly. Mapping these cases to further log levels isn't really practical. Introduce boolean log flags to represent them, instead of abusing log priorities.
