I don't like the idea that the release makefile could perform a newfs on some partition if some environment variable happens to be set either... I'd vote against the patch. And _if_ the patch gets included, it should be made a bit more sophisticated. For example, it should check whether soft- updates was enabled on the partition, and re-enable it after the newfs. Otherwise the whole make release could run slower than without the patch...
