| Summary: | |
| The network file system (nfs) can be used and configured to share a server | |
| disk with a client. For example, a server with the file system /home | |
| can be made available as /home on the client server, given that the | |
| host server is running. Additionally, this file system can be renamed on the client, | |
| however this is generally not good practice and using the same name is recommended. | |
| Permissions can also be set on the server, restricting read, write, execute | |
| on the client server as needed. |
