I first did a clean install (from cdrom) of 7.2 sleecting custom with default + kde + development + etc. I then did an nfs upgrade to 7.2.90. I seem to get a number of "extra" packages installed. This includes asts-devel, brahms, cups, cups-libs, emacs, emacs-el, and hesiod. Of these, only cups-libs was required by another package (kdelibs). To me this is an error. In addition, since LPRng is still the "default" even is cups is being shipped, kdelibs should not require it. Furthermore, both LPRng (lpd) and cups (cups) are being started at boot time.
This is mostly due to files moving between packages and anaconda being smart and brining the new packages along for the upgrade. The cups and LPRng both starting mess should all be better by beta 3
There are still a few oddities, but things are pretty clean now. Closing out.
