RHEL 7.2 KickStart %pre tty3?

I have run into a problem when using a kickstart script on a 7.2 installation. During the %pre portion of the kickstart I do the following:

chvt 3
exec  /dev/tty3 > /dev/tty3 2>/dev/tty3

Pretty standard; works for everything less than 7.2. In order to facilitate debugging I have function defined as follows which allows me to pause the kickstart process if I need to;

# Pause function handle pausing if ${DEBUG} = true
function pause()
{
  local continue=
  while [ "${continue}" != "yes" ]; do
    read -p "Paused; Continue? " continue
    echo ""
  done
}

While I examine the TTY it always shows TTY3 (as expected) none of the output from the script is returned to the desired TTY. Anyone have any tips regarding my issue?
