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...
Regards
Oliver
