2 tristate "NFS client support"
6 select NFS_ACL_SUPPORT if NFS_V3_ACL
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
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.
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.
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
33 bool "NFS client support for NFS version 3"
36 This option enables support for version 3 of the NFS protocol
37 (RFC 1813) in the kernel's NFS client.
42 bool "NFS client support for the NFSv3 ACL protocol extension"
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.
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.
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
64 bool "NFS client support for NFS version 4 (EXPERIMENTAL)"
65 depends on NFS_FS && EXPERIMENTAL
66 select RPCSEC_GSS_KRB5
68 This option enables support for version 4 of the NFS protocol
69 (RFC 3530) in the kernel's NFS client.
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/.
78 bool "Root file system on NFS"
79 depends on NFS_FS=y && IP_PNP
81 If you want your system to mount its root file system via NFS,
82 choose Y here. This is common practice for managing systems
83 without local permanent storage. For details, read
84 <file:Documentation/filesystems/nfsroot.txt>.
86 Most people say N here.
89 bool "Provide NFS client caching support (EXPERIMENTAL)"
90 depends on EXPERIMENTAL
91 depends on NFS_FS=m && FSCACHE || NFS_FS=y && FSCACHE=y
93 Say Y here if you want NFS data to be cached locally on disc through
94 the general filesystem cache manager
