In my point of view, Jeff is just confused by your misunderstanding
of virtual provides.
You've created a case where you expect unison227 to update
unison213. That's exactly what you expect when you expect that "yum
install unison" will install the virtual "unison" pkg in unison227, which
is higher than the virtual unison pkg in unison213.
Further, the Obsoletes/Provides pair in unison213 is wrong+questionable.
You've got:
unison213
obsoletes:
unison < 2.27.57-3
provides:
unison = 2.13.16-9.fc8.3
It obsoletes *itself* because the obsoletes tag covers a much higher
version range than what is provided. The unison227 package obsoletes
the same range, so you have two packages competing with eachother here,
too. Instead, unison213 ought to obsolete at most "unison <= 2.13".

No, but you hoped it would compare the EVR of the virtual packages
instead and effectively treat the two packages as upgradeable, see above.
