Bug#96884: Asks to delete downloaded .deb files even if contains only file: sources

[Tim Cutts <tim.cutts@incyte.com>]

Package: apt
Version: 0.5.3
Severity: normal

My apt/sources.list file contains only mirrors available over NFS (or
sometimes on the local disk itself), such as:

deb file:/home/debian sid main contrib non-free
deb file:/home/debian-non-US sid non-US/main non-US/contrib non-US/non-free

Apt therefore installs packages directly, and doesn't download anything.
So why does it ask the question:

Do you want to erase any previously downloaded .deb files? [Y/n] 

It used not to do this, but I don't remember when it started.  It's an
unnecessary (and irritating!) question if one isn't using ftp or http to
access the packages.

I'm using all default settings; the only configuration file I've altered
is /etc/apt/sources.list

Tim.
