 If it's the feature I think you are talking about, it is also in
RHEL-5/CentOS-5. But it only alters install (actually just changes the
behaviour of compare_providers¹).
 AFAIK that doesn't solve the entire set of problems that Les/Dag want
solved.

 Adding more logic based on "repoid of the installed package" is
somewhat problematic, due to anaconda using different repoids and the
fact there are a number of "repos" in the wild which are just URLs (so
clients have semi-random repoids).

 The known "plans" atm. are more of the "make the priorities plugin suck
less" variety, than to add vendor/buildtime/repoid/etc. directly into
update calculations.
