If you are attempting to mount the mounted filesystem things
could get strange as the host system does it's thing.

Perhaps export /mnt then nfs mount /mnt.
With that done the local mounting and unmounting of
the CDROM could look like adding and deleting 
a directory not a filesystem.

It is unclear to me what happens with NFS when the exported dir
vanishes and reapears.

There is always some confusion if you have a file in a dir
open then mount a filesystem on top of it.
