Ahh.. this would explain why 'fuser -m /coda' doesn't work..

Can we update the coda howto with this?

I'm going to take this opportunity to whine that Coda documentation is
often stale, and the commands don't usually have helpfull useage
messages or manpages ;)

cfs help, in particular ought to not have any references to things we
know don't work (like 'cfs wbstart', or 'cfs fr')
