| 1705 | If you want your Linux box to act as an NFS *server*, so that other |
| 1706 | computers on your local network which support NFS can access certain |
| 1707 | directories on your box transparently, you have two options: you can |
| 1708 | use the self-contained user space program nfsd, in which case you |
| 1709 | should say N here, or you can say Y and use the kernel based NFS |
| 1710 | server. The advantage of the kernel based solution is that it is |
| 1711 | faster. |
| 1712 | |
| 1713 | In either case, you will need support software; the respective |
| 1714 | locations are given in the file <file:Documentation/Changes> in the |
| 1715 | NFS section. |
| 1716 | |
| 1717 | If you say Y here, you will get support for version 2 of the NFS |
| 1718 | protocol (NFSv2). If you also want NFSv3, say Y to the next question |
| 1719 | as well. |

| 2091 | replication, security model for authentication and encryption, |
| 2092 | persistent client caches and write back caching. |
