I'm not entirely sure why you just copy Packages files, but you could
just do the query for Packages with indextargets and copy them over into
$ROOT.

for file in $(apt-get indextargets --format '$(FILENAME)' "Created-By: Packages"); do
	mkdir -p $ROOT/"$(dirname "$file")"
	cp "$file" "$ROOT/$file"
done

(grr, quoting)

But I guess you also have to copy Release files, I don't see how that
works well with APT currently. But we don't store Release files
compressed, so it's sort of OK. Why not just copy everything?
