Not guaranteed, but it works within a massively more constrained environment and so certain fundamental issues don't apply. yum distro-sync requires that all currently running applications are able to deal with their files being replaced. Preupgrade doesn't. That's a pretty obvious distinction, and it's why preupgrade is supportable in a way that yum isn't. -- Matthew Garrett | mjg59@xxxxxxxxxxxxx -- devel mailing list devel@xxxxxxxxxxxxxxxxxxxxxxx https://admin.fedoraproject.org/mailman/listinfo/devel
