mount -f does not enable softupdates.  The mount(8) man page says:

     -f      Forces the revocation of write access when trying to downgrade a
             filesystem mount status from read-write to read-only.  Also
             forces the R/W mount of an unclean filesystem (dangerous; use
             with caution).

In this case, dangerous means that further file system damage and/or a
system panic can happen.


Softupdates is enabled and disabled with
	tunefs -n enable
and
	tunefs -n disable
on an unmounted file system.
