Lets suppose I do the upgrade (from fc3t3)  to FC3 when it comes out.  I 
make sure that the version numbers of the packages I have
are such that they are >= version numbers of FC3 (some of them will be 
higher probably if I am doing daily updates from rawhide).
Now is that enough to say that I have a pristine FC3 system ?

I think the answer is no. Because there might be features that a clean 
process installs that may not happen if I do the upgrade.
Case in point, the default install in FC3t3 enables LVM and partitions 
using LVM. When I did the upgrade from FC2 to FC3t3 on my system,
I did not see the option at all. On another machine where I did a clean 
install, anaconda used LVM to set up partitions.

Is my understanding of the situation correct ?

In other words, is package compatibility equivalent to clean installs ?

Sorry, if this is a stupid question.
