There's some logic in there you could steal which ensures that the current state is preserved on upgrade.

If someone made the decision to disable this, that decision should be respected. Alec PS - use the current Fedora yum-cron as a baseline for anything, the EPEL version is frozen at an ancient state to avoid CentOS conflicts. Just so ya'll know, I didn't mean to be so terse, I'm just currently at a place with very poor internet connection, and that was about all I could reply with. I'll take a look at the specs that you are talking about when I get a better internet connection. We will be looking indepth at how we do automatic updates in SL6. But our phillosophy has always been that out of the box, it should do automatic updates. Then if an adminstator is good enough that they know what they are doing, there should be a way for them to disable or alter the automatic updates. But you are correct, these last yum-conf updates should not have changed whatever you had set in chkconfig. If we ever have to do this mass yum-conf update again, we will have that fixed. When I get to a decent internet connection area, I'll investigate and fix up the spec files so this will hopefully not happen again.
