any idea if (when?) a new version of those RPMs with rollback included will become available for CentOS 4?
it scarcely matters -- rpm rollback is a essentially unattainable mirage, due to the unbounded nature of %pre and %post actions possible.
I wouldn't go that far (though obviously I understand the issues from the previous email). My goal with autorollback and a few patchs to the regular rollback code was to make it possible to rollback (automatically) a failed upgrade. That said scriptlets may in some cases need changing to work properly/intuitavily in a rollback transaction.
For the most part, because RedHat scriptlets are typically drop dead simple I do see any issues with their packages in a rollback. The way RedHat does scriptlets is really the best way to do them (that is as little as necessary), but sometimes you get a package from some other source (or maybe your own...we all have our reasons) that is a bit more complex. It is these complex scriptlets that need to take the possibility of a rollback into account.
So in short, I don't think rollback feature is that useless, but I really don't think it or the package universe it supports is completely there yet either.
