Hmmm, after reading this, I don't think either hard or soft actually 
unmounts the fs.  It looks like all these do is send messages to the 
software that the resource is unavailable.  Which actually might be just 
as good.  But then I would like the system to report a problematic 
mount.  I was going to do this by testing to see what was mounted, but 
it won't work if it doesn't automatically unmount.

I didn't see the part about  risking data corruption with soft.  In 
fact, it is not clear what the difference between soft and intr are:  
they both report errors to the calling program.  I guess intr lets the 
program decide to stop trying?

It's also unclear as to whether or not the option retrans refers to 
cumulative timeouts, or successive timeouts.  I think successive minor 
timeouts makes more sense.  It seems I might want to set this one also.
