I've enabled softupdates on / (/ being a 750 MB filesystem, about 60% 
full, containing /, /usr, and /var) on a couple machines at work.  I 
also use softupdates on one of my machines at home, however on that 
system I do not use softupdates on / and /usr (on different disks) 
because they're hardly written to.  I've  had no problems with data
integrity or system availability due to softupdates (knock on wood).
