As I said (in an aside) in the original message, the following
sequence also will demonstrate the lossage.

boot netbsd -s
# tunefs -N /dev/rwd0a		# reports softdeps enabled
# tunefs -n disable /dev/rwd0a
# tunefs -N /dev/rwd0a		# reports softdeps disabled
# reboot
And when the system comes up multiuser
# tunefs -N /dev/rwd0a		# reports softdeps enabled

Somehow, when the root_device is mounted readonly, the changes appear
to take place, but then mounting the filesystem rw *through any means*
will result in the old state being restored.
