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

| bool "NFS client support for NFS version 3" | |

| This option enables support for version 3 of the NFS protocol | |
| (RFC 1813) in the kernel's NFS client. | |
| If unsure, say Y. | |
| config NFS_V3_ACL | |
| bool "NFS client support for the NFSv3 ACL protocol extension" | |
| depends on NFS_V3 | |
| help | |
| Some NFS servers support an auxiliary NFSv3 ACL protocol that | |
| Sun added to Solaris but 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 | |
| ACLs on local files whether this protocol is available or not. | |
| Choose Y here if your NFS server supports the Solaris NFSv3 ACL | |
| protocol extension and you want your NFS client to allow | |
| applications to access and modify ACLs on files on the server. | |
| Most NFS servers don't support the Solaris NFSv3 ACL protocol | |
| extension. You can choose N here or specify the "noacl" mount | |
| option to prevent your NFS client from trying to use the NFSv3 | |
| ACL protocol. | |
| If unsure, say N. | |
| config NFS_V4 | |

| help | |
| This option enables support for version 4 of the NFS protocol | |
| (RFC 3530) in the kernel's NFS client. | |
| To mount NFS servers using NFSv4, you also need to install user | |
| space programs which can be found in the Linux nfs-utils package, | |
| available from http://linux-nfs.org/. | |

| If you want your system to mount its root file system via NFS, | |
| choose Y here. This is common practice for managing systems | |
| without local permanent storage. For details, read | |
| <file:Documentation/filesystems/nfsroot.txt>. | |
| Most people say N here. |
