Open System Services NFS Overview

Figure 1 Example of UNIX Locally Mounted Hierarchy
First you create and mount the root directory. After you create the /etc and /usr directories,
you can mount the subtrees for these directories. Finally, you create the /usr/lib directory and
mount its subtree of files.
In addition to performing local mounts, you can perform remote mounts of directories locally
mounted on some other system on the network. The example in Figure 2 (page 12) shows a UNIX
system named systwo, which has a /usr/lib/src directory mounted locally. You can create
a /usr/src directory on UNIX sysone and perform a remote mount to access the /usr/lib/src
directory on systwo as follows:
mkdir /usr/src
mount -t nfs /usr/src systwo:/usr/lib/src
