Comment 19 for bug 525674

Thanks for working on this! Diff looks good (pitti pointed some minor things out already).

One more thing, please keep the part:
  "DPkg::Post-Invoke {"if [ -d /var/lib/update-notifier ]; then touch /var/lib/update-notifier/dpkg-run-stamp; fi; "
the part of update-notifier that displays a icon (used in xfce iirc) will depend on this file, it uses inotify to know reliable when apt was finished.
