Wherever possible, change these “stepping-stone” mounts so that
whole directories are mounted from a single NFS server.
Stepping-stone (hierarchical) mounts, like the one in the example
above, cause more NFS requests than mounts from a single server. In
the example, if a client wants access to something in
/usr/share/lib, a request must be sent to server thyme, then to
server basil, and finally to server sage.
