You should definitely use soft-updates.

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...
