I agree.

I believe, with growfs, the space that you add must be contiguous
with the partition it is joining.   So, unless there is a partition
that could be shrunk next to root, (maybe swap is there) it wouldn't work.
If there is room - maybe by mucking with swap if it is the next partition,
then it might be do-able.  But, I would also be leary of doing it with /.
