2 tristate "NFS client support"
3 depends on INET && FILE_LOCKING
4 depends on BKL # fix as soon as lockd is done
7 select NFS_ACL_SUPPORT if NFS_V3_ACL
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
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.
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.
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
34 bool "NFS client support for NFS version 3"
37 This option enables support for version 3 of the NFS protocol
38 (RFC 1813) in the kernel's NFS client.
43 bool "NFS client support for the NFSv3 ACL protocol extension"
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.
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.
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
65 bool "NFS client support for NFS version 4"
69 This option enables support for version 4 of the NFS protocol
70 (RFC 3530) in the kernel's NFS client.
72 To mount NFS servers using NFSv4, you also need to install user
73 space programs which can be found in the Linux nfs-utils package,
74 available from http://linux-nfs.org/.
79 bool "NFS client support for NFSv4.1 (EXPERIMENTAL)"
80 depends on NFS_V4 && EXPERIMENTAL
82 This option enables support for minor version 1 of the NFSv4 protocol
83 (draft-ietf-nfsv4-minorversion1) in the kernel's NFS client.
88 bool "Root file system on NFS"
89 depends on NFS_FS=y && IP_PNP
91 If you want your system to mount its root file system via NFS,
92 choose Y here. This is common practice for managing systems
93 without local permanent storage. For details, read
94 <file:Documentation/filesystems/nfs/nfsroot.txt>.
96 Most people say N here.
99 bool "Provide NFS client caching support"
100 depends on NFS_FS=m && FSCACHE || NFS_FS=y && FSCACHE=y
102 Say Y here if you want NFS data to be cached locally on disc through
103 the general filesystem cache manager
105 config NFS_USE_LEGACY_DNS
106 bool "Use the legacy NFS DNS resolver"
109 The kernel now provides a method for translating a host name into an
110 IP address. Select Y here if you would rather use your own DNS
115 config NFS_USE_KERNEL_DNS
117 depends on NFS_V4 && !NFS_USE_LEGACY_DNS
