I notice /dev/kmsg documented but no longer appears, but /dev/log[=] exists if syslog-ng is running; and /dev/pipe and /dev/fifo are mentioned but don't exist. -- Take care. Thanks, Brian Inglis, Calgary, Alberta, Canada This email may be disturbing to some readers as it contains too much technical detail.
