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

31 If unsure, say N.

38 (RFC 1813) in the kernel's NFS client.

42config NFS_V3_ACL
43 bool "NFS client support for the NFSv3 ACL protocol extension"
44 depends on NFS_V3
45 help
46 Some NFS servers support an auxiliary NFSv3 ACL protocol that
47 Sun added to Solaris but never became an official part of the
48 NFS version 3 protocol. This protocol extension allows
49 applications on NFS clients to manipulate POSIX Access Control
50 Lists on files residing on NFS servers. NFS servers enforce
51 ACLs on local files whether this protocol is available or not.
52
53 Choose Y here if your NFS server supports the Solaris NFSv3 ACL
54 protocol extension and you want your NFS client to allow
55 applications to access and modify ACLs on files on the server.
56
57 Most NFS servers don't support the Solaris NFSv3 ACL protocol
58 extension. You can choose N here or specify the "noacl" mount
59 option to prevent your NFS client from trying to use the NFSv3
60 ACL protocol.
61
62 If unsure, say N.

68 This option enables support for version 4 of the NFS protocol
69 (RFC 3530) in the kernel's NFS client.
70
71 To mount NFS servers using NFSv4, you also need to install user
72 space programs which can be found in the Linux nfs-utils package,
73 available from http://linux-nfs.org/.

92 without local permanent storage. For details, read
