But why cannot there be a group of updates based on the new python or 
the new X?  How do others manage these changes?  Not all packages depend 
on python or X so not all packages need to be updated.  There must be 
some support for python2.4 in 2.5 or that would require a major change 
and I would expect the numbering to change to 3.0.

Don't get me wrong, I do understand this reasoning.  I have tried the 
upgrade via yum path with headaches and will stick with the clean 
install from that point on.

I have seen Ubuntu systems installed and upgraded to current versions 
very easily.
