| 11 | Choose Y here if you want to allow other computers to access |

| 13 | protocol. To compile the NFS server support as a module, |

| 16 | You may choose to use a user-space NFS server instead, in which |
| 17 | case you can choose N here. |

| 19 | To export local file systems using NFS, you also need to install |

| 50 | Solaris NFS servers support an auxiliary NFSv3 ACL protocol that |
| 51 | never became an official part of the NFS version 3 protocol. |
| 52 | This protocol extension allows applications on NFS clients to |
| 53 | manipulate POSIX Access Control Lists on files residing on NFS |
| 54 | servers. NFS servers enforce POSIX ACLs on local files whether |
| 55 | this protocol is available or not. |

| 57 | This option enables support in your system's NFS server for the |
| 58 | NFSv3 ACL protocol extension allowing NFS clients to manipulate |
| 59 | POSIX ACLs on files exported by your system's NFS server. NFS |
| 60 | clients which support the Solaris NFSv3 ACL protocol can then |
| 61 | access and modify ACLs on your NFS server. |
| 62 | |
| 63 | To store ACLs on your NFS server, you also need to enable ACL- |
| 64 | related CONFIG options for your local file systems of choice. |
