Yes, that's true for my installation of Fedora 14 too.  About 80% of
my packages are new in Fedora 14, with 9% and 7% from Fedora 12 and 13
respectively and a handful from older one too.  I still have nearly
three times as many yumdb entries than the number of RPMs currently
installed, which must be for old packages.

Thanks,
Mike
