>Description:
/sbin/sysctl does not return anything printable upon request
(sysctl -n ${mib}) of a non-existent variable, just an error-code.
The code in 'elif' clause in /etc/rc.d/sysctl
elif [ "$1" -eq "last" ]; then
warn "sysctl ${mib} does not exits."
fi
is probably wrong
>How-To-Repeat:
Put a non-existent variable in /etc/sysctl.conf
and reboot. There will be message like (taken from /var/log/console.log)
