It does not look like it is a prerequisite to have SU enabled when you  
want to enable SUJ. So I assume SUJ implies SU, and as such I think  
you can agree that it is not easy to determine at disable time of SUJ,  
if the FS was SU before or not.

There may be not much people which run UFS without SU, but for those  
which do, I'm sure it would be a surprise if they disable SUJ and do  
not get back to plain UFS without SU.

So whatever the consensus is (disabling SUJ does or dosn't enable SU),  
the man page needs to tell what it does.

Bye,
Alexander.
