Though is not complicated to do, it has become an expensive operation to perform. So it would be nice for me and for those of us who need to disable this feature to have an option to disable it in yast. It would be nice to see it in the same tab in which one can disable ipv6. -- openSUSE Feature: https://features.opensuse.org/306646
