 When you reboot Linux the login message and the /etc/issue file you've just edited will return to the default. To prevent this, enter:
 su -c "pico /etc/rc.d/rc.local" ...and begin each of the following lines (indicated in bold) with a hash (#) character so that Linux ignores them. If at any time you want the default login message to return, simply remove the offending hash characters.
 # 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)" >> /etc/issue
 
 # cp -f /etc/issue /etc/issue.net
 # echo >> /etc/issue
 fi
