           Summary: Hide harmless kernel messages from console
           Product: Linux From Scratch
           Version: CVS
          Platform: PC
               URL: http://www.linuxfromscratch.org/lfs/view/cvs/chapter07/s
        OS/Version: All
            Status: UNCONFIRMED
          Severity: normal
          Priority: P5
         Component: Book
        AssignedTo: lfs-book at linuxfromscratch.org
        ReportedBy: dirk.kleinschmidt at gmx.net
         QAContact: lfs-book at linuxfromscratch.org


When I'm running the my firewall (build from the blfs-book) all log-messages 
are posted to /var/log/kern.log and to the active console. To avoid kernel 
messages that are non-critical to be displayed on console I recommend to 
replace "loadproc klogd" with "loadproc klogd -c 1" in $rc_base/init.d/sysklogd.

This is not only a problem of the firewall itself but those kernel messages 
also appear when the network cable is disconnected from the network-card. In my 
eyes those informal messages are best stored in the logfiles.

The values for the parameter "-c" can be found in /usr/include/linux/kernel.h. 
Search for KERN_EMERG to see the values (0-7) for this parameter.
