| 8 | Choose Y here if you want to access files residing on other | |
| 9 | computers using Sun's Network File System protocol. To compile | |
| 10 | this file system support as a module, choose M here: the module | |
| 11 | will be called nfs. | |
| 12 | ||
| 13 | To mount file systems exported by NFS servers, you also need to | |
| 14 | install the user space mount.nfs command which can be found in | |
| 15 | the Linux nfs-utils package, available from http://linux-nfs.org/. | |
| 16 | Information about using the mount command is available in the | |
| 17 | mount(8) man page. More detail about the Linux NFS client | |
| 18 | implementation is available via the nfs(5) man page. | |
| 19 | ||
| 20 | Below you can choose which versions of the NFS protocol are | |
| 21 | available in the kernel to mount NFS servers. Support for NFS | |
| 22 | version 2 (RFC 1094) is always available when NFS_FS is selected. | |
| 23 | ||
| 24 | To configure a system which mounts its root file system via NFS | |
| 25 | at boot time, say Y here, select "Kernel level IP | |
| 26 | autoconfiguration" in the NETWORK menu, and select "Root file | |
| 27 | system on NFS" below. You cannot compile this file system as a | |
| 28 | module in this case. | |

| 42 | bool "NFS client support for the NFSv3 ACL protocol extension" | |
| 43 | depends on NFS_V3 | |
| 44 | help | |
| 45 | Some NFS servers support an auxiliary NFSv3 ACL protocol that | |
| 46 | Sun added to Solaris but never became an official part of the | |
| 47 | NFS version 3 protocol. This protocol extension allows | |
| 48 | applications on NFS clients to manipulate POSIX Access Control | |
| 49 | Lists on files residing on NFS servers. NFS servers enforce | |
| 50 | ACLs on local files whether this protocol is available or not. | |
| 51 | ||
| 52 | Choose Y here if your NFS server supports the Solaris NFSv3 ACL | |
| 53 | protocol extension and you want your NFS client to allow | |
| 54 | applications to access and modify ACLs on files on the server. | |
| 55 | ||
| 56 | Most NFS servers don't support the Solaris NFSv3 ACL protocol | |
| 57 | extension. You can choose N here or specify the "noacl" mount | |
| 58 | option to prevent your NFS client from trying to use the NFSv3 | |
| 59 | ACL protocol. | |

| 69 | ||
| 70 | To mount NFS servers using NFSv4, you also need to install user | |
