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. | |
14 | ||
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 | |
22 | exports(5) man page. | |
23 | ||
24 | Below you can choose which versions of the NFS protocol are | |
25 | available to clients mounting the NFS server on this system. | |
26 | Support for NFS version 2 (RFC 1094) is always available when | |
27 | CONFIG_NFSD is selected. | |
28 | ||
29 | If unsure, say N. | |

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. | |

65 | If unsure, say N. | |

75 | This option enables support in your system's NFS server for | |
76 | version 4 of the NFS protocol (RFC 3530). | |
77 | ||
78 | To export files using NFSv4, you need to install additional user | |

87 | help | |
88 | ||
89 | Say Y here if you want enable fine-grained security label attribute | |
90 | support for NFS version 4. Security labels allow security modules like | |
91 | SELinux and Smack to label files to facilitate enforcement of their policies. | |
92 | Without this an NFSv4 mount will have the same label on each file. | |
93 | ||
94 | If you do not wish to enable fine-grained security labels SELinux or | |
95 | Smack policies on NFSv4 files, say N. | |
96 | ||
97 | WARNING: there is still a chance of backwards-incompatible protocol changes. | |
cce6de90 | 98 | For now we recommend "Y" only for developers and testers. |
