Human interaction in %PRE text mode with snack Dialog boxes

["Meyers, John J" <john j meyers boeing com>]

Hi All,

        The %pre mode seems to conduct I/O with tty3. With primary anaconda user interaction displays on tty1. I need to interact with the user on tty1 during %pre; Using python and snack. Due to using various weird hardware in our environment a graphical install dos not work.

 The Code below is just an example of what I've tried.

 

%pre --interpreter /usr/bin/python
TTY = 1
import os
import sys
import snack
import time
import fcntl
import termios
os.system("chvt %d" % TTY)
fd = os.open("/dev/tty%d" % TTY, os.O_RDWR)
os.dup2(fd, 0)
os.dup2(fd, 1)
os.dup2(fd, 2)
sys.stdin = os.fdopen(0, "r")
sys.stdout = os.fdopen(1, "w")
sys.stderr = os.fdopen(2, "w")
screen = snack.SnackScreen()

snack.ButtonChoiceWindow(screen, "WARNING",
    "WARNING! Am I CRAZY!",
    buttons=["reboot", "continue"]):
    os.system("reboot")
    while 1: time.sleep(10)
screen.finish()
os.system("chvt %d" % 3)
%end

ANY suggestions??
