From 1e4dd3b87be8e06dd0ae1c4b2c250591b615a2e1 Mon Sep 17 00:00:00 2001
From: Joey Hess <joey@kodama.kitenet.net>
Date: Mon, 7 Jan 2008 13:46:21 -0500
Subject: * Separate debconf use from the main flow of the script so the commit
   stage can use editors etc. Closes: #459547 * Remove the hint about setting
 -e to get interactive commits, since   I don't want to encourage users to do
 that. (For one thing, it's unlikely   to work if a graphical package manager
 is used..)
