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