| Item | Description |

| -a spot=Value | Specifies the SPOT resource to be used to provide network boot support and the /usr file system for clients. |
| -a root=Value | Specifies the root resource that contains the client root (/) directories. The root resource must be served by the same machine that serves the SPOT. |
