+//config:	  klogd is a utility which intercepts and logs all
+//config:	  messages from the Linux kernel and sends the messages
+//config:	  out to the 'syslogd' utility so they can be logged. If
+//config:	  you wish to record the messages produced by the kernel,
+//config:	  you should enable this option.

+//config:	help
+//config:	  The klogd applet supports two interfaces for reading
+//config:	  kernel messages. Linux provides the klogctl() interface
+//config:	  which allows reading messages from the kernel ring buffer
+//config:	  independently from the file system.
+//config:
+//config:	  If you answer 'N' here, klogd will use the more portable
+//config:	  approach of reading them from /proc or a device node.
+//config:	  However, this method requires the file to be available.
+//config:
+//config:	  If in doubt, say 'Y'.
