You must be kidding. LOG_CONS is there for a reason -- in case syslogd
isn't running and output has to go SOMEwhere.
Of couse, LOG_CONS should be specified to write to the console only
IFF writing to /dev/log blocks or fails. Either that, or syslog(3)
should write to the console in that case by default...Hmmm.
