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.

This option enables support for version 3 of the NFS protocol

|
|
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.

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 unsure, say N.

Unless you're an NFS developer, say N.

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.
