I had problems with "apt-get upgrade" in the past. I don't remember
what, but this may be what the apt-get man page describes: "under no
circumstances are currently installed packages removed, or packages
not already installed retrieved and installed." This is not what I
want. For instance, it should be fine to remove transitional packages.

For instance, "apt-get dist-upgrade" says that apache2.2-common
libapache2-svn will be removed (due to the 2.2 -> 2.4 apache2
transition). It is not OK, because libapache2-svn should not be
removed. Using "apt-get upgrade" isn't OK either, because if I
understand correctly, it will never accept to remove apache2.2-common
(as this is a 2.2 related package as its name says).
