  7         help
  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.
 29 
 30           If unsure, say N.

 37           This option enables support for version 2 of the NFS protocol
 38           (RFC 1094) in the kernel's NFS client.
 39 
 40           If unsure, say Y.

 53         bool "NFS client support for the NFSv3 ACL protocol extension"
 54         depends on NFS_V3
 55         help
 56           Some NFS servers support an auxiliary NFSv3 ACL protocol that
 57           Sun added to Solaris but never became an official part of the
 58           NFS version 3 protocol.  This protocol extension allows
 59           applications on NFS clients to manipulate POSIX Access Control
 60           Lists on files residing on NFS servers.  NFS servers enforce
 61           ACLs on local files whether this protocol is available or not.
 62 
 63           Choose Y here if your NFS server supports the Solaris NFSv3 ACL
 64           protocol extension and you want your NFS client to allow
 65           applications to access and modify ACLs on files on the server.
 66 
 67           Most NFS servers don't support the Solaris NFSv3 ACL protocol
 68           extension.  You can choose N here or specify the "noacl" mount
 69           option to prevent your NFS client from trying to use the NFSv3
 70           ACL protocol.
 71 
 72           If unsure, say N.

 80           This option enables support for version 4 of the NFS protocol
 81           (RFC 3530) in the kernel's NFS client.
 82 
 83           To mount NFS servers using NFSv4, you also need to install user
 84           space programs which can be found in the Linux nfs-utils package,
 85           available from http://linux-nfs.org/.
 86 
 87           If unsure, say Y.

102           This option enables support for minor version 1 of the NFSv4 protocol
103           (RFC 5661) in the kernel's NFS client.

136           This option defines the domain portion of the implementation ID that
137           may be sent in the NFS exchange_id operation.  The value must be in
138           the format of a DNS domain name and should be set to the DNS domain
139           name of the distribution.
140           If the NFS client is unchanged from the upstream kernel, this
141           option should be set to the default "kernel.org".

148           This option makes the NFS client advertise to NFSv4.1 servers that
149           it can support NFSv4 migration.
150 
151           The NFSv4.1 pieces of the Linux NFSv4 migration implementation are

163           If you want your system to mount its root file system via NFS,
164           choose Y here.  This is common practice for managing systems
165           without local permanent storage.  For details, read
166           <file:Documentation/filesystems/nfs/nfsroot.txt>.
