From 7198d218be23bce02a8daf530563d3cb3d499691 Mon Sep 17 00:00:00 2001
From: "CanbiZ (MickLesk)" <47820557+MickLesk@users.noreply.github.com>

Subject: [PATCH] Let var_* answer the optional add-on prompts (#17858)

Thirty-six yes/no prompts for optional components in 26 install
scripts could only be answered at the terminal, so an unattended
install stopped at the first one. Each now takes var_<app>_<option>
first and still asks when it is unset. The four conditions that only
matched a single y now take yes as well, since that is what the website
sends.
