[Rpm-maint] [Suse-patch] Revert provides as obsoletes behavior

[Florian Festi]

Hi!

I have had a look at the obsolete behavior topic from a RHEL perspective. I 
checked all obsoletes in RHEL 3, 4  and 5 against the same and the previous 
release and filtered all that match against provides. For the results see 
the attachments.

Reading the problem descriptions I have the suspicion that the problem is 
not that obsoletes match against provides but that rpm uses the obsolete 
mechanism to do updates - to find the packages it needs to remove to be more 
precise. This was fine as long as obsoletes just matched against pkg names 
which is what the update should do, too. But with the "new" obsolete 
behavior updates and obsoletes are different and should uses different code 
paths.
If this is true (I have to admit that I did not look into the code) fixing 
the update behavior would be the way to go IMHO and not altering the 
actually unrelated obsolete handling.
