Environment is FreeBSD 7.2  i386

I have a Berkeley FFS filesystem that is mounted ro at boot time.

If I do a 'mount -u' to make it writable, it _is_ made writable, but
"soft-updates' is also set.   Incidentally, does anybody know _where_
the 'soft-updates' optioon is documented??  I've looked evereywhere I
can think of, brute-force grepped wholee sections of the /usr/share/man
directory tree, all without succeess.

If I use 'mount -u -r' to return it to the readonly state, 'soft-updates' is
*still* set.

_HOW_ do I make'soft-updates' go away on a mounted filesystem ??

'umount' and then 'mount' does the trick, but it is no a viable production'
option.

THe underlying situation -- the need to make the filesystem writable -- comes
up only rarely, and it doesn't seem to hurt anything if the filesystem is
left with soft-updates set, but I _would_ like to clear it, because it *is*
logically inconsistant with the read-only status of the filesystem.

Anybody got a bright idea I haven't thought of?
