Question, does umount still unmount "one instance" of the mount?  This 
is the behavior under Red Hat Enterprise 3 (2.4 kernel) which also 
doesn't complain.  The application I QA hasn't managed to get confused 
enough under RHEL4 (we start supporting RHEL4 under our next release) to 
mount one of our mount points multiple times so I don't have a data 
point for RHEL4 (2.6 kernel).

Under RHEL3, I just keep issuing umounts for the mount point until I get 
rid of all of them.  Would this work for your situation?  Any idea when 
this "feature" got added to mount/umount?

Cheers,
Dave
