reading user input in %pre script no longer working

[Ben Grommes]

My kickstart script reads user input in the %pre scriptlet using the read
command.  This worked fine in CentOS 4.4, but in CentOS 4.5 it no longer works.
 It appears that the read command is not taking input from the console.

I'm doing a headless mode install (text option in ks.cfg).

Here is my %pre script:

%pre
install="no"
while [ "$install" != "yes" ]; do 
    (
    echo -n "Proceed with install? "
    )>/dev/tty1
    read install
done

The output of the echo shows up on the screen, but the read command doesn't
accept any input from the keyboard.

Any suggestions for how to debug this would be appreciated.
