What about the cleanup scripts or removing old files? Looks to me
like all that is only done at the very end right now. Maybe completing
individual package updates in one step before updating the next
package should be an option for users.
again - once this is handed off to ts.run() yum only reports what rpm
does. so if this is going to be an option (which I think is a bit silly,
tbh) it would need to be supported in rpm, first.
