I did different installations of Beta3, one with KDE and 2 with Gnome, all from the DVD. In individual package selection I took great care to setup KDE without any Gnome packages and vice versa.
So I was really surprised to see the first update run of the fresh Gnome system - around 500 packages altogether, which is not surprising. Surprising is the large number of KDE packages (roughly around 130)! There were even large ones like kde4-wallpapers, several KDE games and handbooks and lots of KDE libraries. Even kde4-desktop and others. I can not understand how such packages could be dependencies of a pure Gnome installation.
I know, I should give a list of all "surprising" packages for a proper report but I think this would be too much (list of all installed packages). That's why I did not write a bug report but posted here, my be somebody has an explanation.
After the update (remember: first update after installation!) I was informed that more than 180 packages were now "orphans" - how could that be directly after installation + updates? And now the surprise: almost all orphans were KDE packages! Causes the question: why were they installed in the first place? If they are orphans now although I did not de-install anything, they could not have been installed because of dependencies!
