  32
  33       dpkg let packages disappear then they have no files any longer and
  34       nothing depends on them. We need to collect this as dpkg as well as
  35       APT doesn't know beforehand that the package will disappear, so the
  36       only possible option is to tell the user afterwards about it.
  37       To enhance the experience we also try to forward the auto-install
  38       flag so the disappear-causer(s) are not autoremoved next time -
  39       for the transfer to happen the disappeared version needs to depend
  40       on the package the flag should be forwarded to and this package
  41       needs to declare a Replaces on the disappeared package.
  42       \param pkgname Name of the package that disappeared
