You could use something like the snippet below. All credit goes to the 
presentation "Kickstart Tips & Tricks" by Chip Shabazian (caution: lines 
may be wrapped).

%pre
#!/bin/sh
exec < /dev/tty3 > /dev/tty3 2>&1
chvt 3
install="no"
while [ "$install" != "yes" ]; do
clear
echo
echo 
'********************************************************************************'
echo '*
W A R N I N G
*'
echo '*

echo ‘*This process will install a completely new operating system and
*‘
echo '*
*'
echo '* Do you wish to continue? (Type the entire word "yes" to proceed.)
*'
echo '*
*'
echo 
'********************************************************************************'
echo
read -p "Proceed with install? " install done clear chvt 1 #%end
