| 10 | Choose Y here if you want to allow other computers to access |
| 11 | files residing on this system using Sun's Network File System |
| 12 | protocol. To compile the NFS server support as a module, |
| 13 | choose M here: the module will be called nfsd. |

| 15 | You may choose to use a user-space NFS server instead, in which |
| 16 | case you can choose N here. |
| 17 | |
| 18 | To export local file systems using NFS, you also need to install |
| 19 | user space programs which can be found in the Linux nfs-utils |
| 20 | package, available from http://linux-nfs.org/. More detail about |
| 21 | the Linux NFS server implementation is available via the |

| 48 | help |
| 49 | Solaris NFS servers support an auxiliary NFSv3 ACL protocol that |
| 50 | never became an official part of the NFS version 3 protocol. |
| 51 | This protocol extension allows applications on NFS clients to |
| 52 | manipulate POSIX Access Control Lists on files residing on NFS |
| 53 | servers. NFS servers enforce POSIX ACLs on local files whether |
| 54 | this protocol is available or not. |
| 55 | |
| 56 | This option enables support in your system's NFS server for the |
| 57 | NFSv3 ACL protocol extension allowing NFS clients to manipulate |
| 58 | POSIX ACLs on files exported by your system's NFS server. NFS |
| 59 | clients which support the Solaris NFSv3 ACL protocol can then |
| 60 | access and modify ACLs on your NFS server. |
| 61 | |
| 62 | To store ACLs on your NFS server, you also need to enable ACL- |
| 63 | related CONFIG options for your local file systems of choice. |
