The pipefs could possibly be mounted even if nothing's using it, also. Got any NFS-related services running?

> unmountnfs.sh is part of initscripts. I don't think you're expected to call it directly, so I'd be inclined to say leave it alone. I think you can try removing all those packages if you really don't need them. To stop nfs-common, you'd use '/etc/init.d/nfs-common stop'.
