>Description:
	When mdmfs run with name mount_mfs it work in compatibility mode.
	flag -S not allowed in compatibility mode, but by default disk created
 with soft-updates turned on.
>How-To-Repeat:
	Try to create memory disk with soft-updates turned off from /etc/fstab.
>Fix:

I see to ways to fix this problem:

1. In compatibility mode turn off soft-updates
(In FreeBSD 4.X mount_mfs by default turn soft-updates off).
