/etc/rc.d/rc.local
tam pishe taka:
     # This will overwrite /etc/issue at every boot.  So,
make any changes you
     # want to make to /etc/issue here or you will lose them
when you reboot.
    echo "" > /etc/issue
    echo "$R" >> /etc/issue
     echo "Kernel $(uname -r) on $a $(uname -m) - \l" >>
/etc/issue

    cp -f /etc/issue /etc/issue.net
    echo >> /etc/issue
