	If I understand correctly, there is only a single bit used, 
and it is used for both indicating whether softupdates should be 
enabled and whether it actually was.  Therefore this is not a 
reliable indicator.

	I believe that the only reason for this is that softupdates 
under NetBSD is not well implemented, and therefore is not 
sufficiently stable to leave turned on.  If/when the NetBSD 
implementation is brought up to the levels where it is under FreeBSD 
that this will be much less of a problem.

	Moreover, the /etc/fstab file is not something you want to 
munge, and encouraging frequent modifications of this file to enable 
or disable softupdates is an incredibly bad idea.
