Grabbing user input in the %pre section using the python snack library

[Matt Rose]

you can kick off a %pre in python using the --interpreter flag.  I just 
use the vt5 for feedback, so I just issue

os.system("chvt 5")

and write to /dev/tty5 directly, but I'm sure you could manipulate 
sys.stdout, and sys.stderr
