Issue

I have a python program to get a user input with TUI by snack, which is used to create a kickstart file dynamically.
In the python script, standard input, output, and error were changed into /dev/tty1
This program worked for Red Hat Enterprise Linux 6, but it doesn't for Red Hat Enterprise Linux 7.
