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

files residing on this system using Sun's Network File System |
|
protocol. To compile the NFS server support as a module, |
|
choose M here: the module will be called nfsd. |

You may choose to use a user-space NFS server instead, in which |
|
case you can choose N here. |
|
|
|
To export local file systems using NFS, you also need to install |
|
user space programs which can be found in the Linux nfs-utils |
|
package, available from http://linux-nfs.org/. More detail about |
|
the Linux NFS server implementation is available via the |
|
exports(5) man page. |

Below you can choose which versions of the NFS protocol are |

available to clients mounting the NFS server on this system. |

Support for NFS version 2 (RFC 1094) is always available when |

CONFIG_NFSD is selected. |

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

This option enables support in your system's NFS server for |

To export files using NFSv4, you need to install additional user |

help |
|

Say Y here if you want enable fine-grained security label attribute |
|
support for NFS version 4. Security labels allow security modules like |
|
SELinux and Smack to label files to facilitate enforcement of their policies. |
|
Without this an NFSv4 mount will have the same label on each file. |
|
|
|
If you do not wish to enable fine-grained security labels SELinux or |
|
Smack policies on NFSv4 files, say N.
