Title:
  Workaround apt-ftparchive generating empty Packages.gz

Status in “debian-cd” package in Ubuntu:
  New

Bug description:
  Hello,

  On my system with apt-ftparchive version 0.9.7.7, empty Packages.gz
  have size 0 instead of 20 bytes for empty gzip file.

  Steps to reproduce:

  1) cat > apt-ftparchive.conf <<EOF
  Dir::ArchiveDir ".";
  Dir::OverrideDir ".";
  Dir::CacheDir ".";
  Default::Packages::Compress "gzip";

  TreeDefault::Contents " ";

  
  Tree "dists/whatever" {
      FileList "empty.list";
      Sections "main";
      Architectures "amd64";
  }
  EOF

  2) > empty.list

  3) mkdir -p dists/whatever/main/binary-amd64

  4) apt-ftparchive generate apt-ftparchive.conf

  5) ls -l dists/whatever/main/binary-amd64/

  This cause troubles installing my custom CDROM, apt-cdrom fails with:

      Mar  1 16:06:15 base-installer: gzip: 
      Mar  1 16:06:15 base-installer: stdin: unexpected end of file

  Then base installer fails to install lvm2 because it does not find it.

  My workaround makes my custom CDROM work again.

  Regards.
