Subject: [PATCH] automated_script: drain stale tty input + drop redundant
 stdin redirect
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Fix the ^[[13;1R cursor-position-report artifacts visible next to the
first configurator step. archiso's boot init leaves DSR responses in the
kernel tty input buffer; the first gum invocation reads them as stray
input and echoes them as visible escape sequences.

- Drain stdin (with a short timeout) from /dev/tty before configurator
  runs so any pending replies are consumed.
- Drop the explicit </dev/tty stdin redirect — the parent script's
  stdin is already tty1 (inherited from archiso autostart), and the
  explicit redirect opened a new fd with subtly different termios.
