Clean up: refresh the help text for Kconfig items related to the NFS
client. Remove obsolete URLs, and make the language consistent among
the options.
Also move the ROOT_NFS config option next to the options related to
the
NFS client.

- If you are connected to some other (usually local) Unix computer
- (using SLIP, PLIP, PPP or Ethernet) and want to mount files
residing
- on that computer (the NFS server) using the Network File Sharing
- protocol, say Y. "Mounting files" means that the client can
access
- the files with usual UNIX commands as if they were sitting on the
- client's hard disk. For this to work, the server must run the
- programs nfsd and mountd (but does not need to have NFS file
system
- support enabled in its kernel). NFS is explained in the Network
- Administrator's Guide, available from
- <http://www.tldp.org/docs.html#guide>, on its man page: "man
- nfs", and in the NFS-HOWTO.
-
- A superior but less widely used alternative to NFS is provided by
- the Coda file system; see "Coda file system support" below.
+ 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.
- If you say Y here, you should have said Y to TCP/IP networking
also.
- This option would enlarge your kernel by about 27 KB.
+ 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.
- To compile this file system support as a module, choose M here:
the
- module will be called nfs.
+ 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.
- If you are configuring a diskless machine which will mount its
root
- file system over NFS at boot time, say Y here and to "Kernel
- level IP autoconfiguration" above and to "Root file system on
NFS"
- below. You cannot compile this driver as a module in this case.
- There are two packages designed for booting diskless machines
over
- the net: netboot, available from
- <http://ftp1.sourceforge.net/netboot/>, and Etherboot,
- available from <http://ftp1.sourceforge.net/etherboot/>.
+ 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 you don't know what all this is about, say N.
+ If unsure, say N.

- Say Y here if you want your NFS client to be able to speak

help
- Implement the NFSv3 ACL protocol extension for manipulating POSIX
- Access Control Lists. The server should also be compiled with
- the NFSv3 ACL protocol extension; see the CONFIG_NFSD_V3_ACL
option.
+ 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.
