				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
				11	will be called nfs.
				12
				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.
				19
				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.
				23
				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
				28	module in this case.

				42	bool "NFS client support for the NFSv3 ACL protocol extension"
				43	depends on NFS_V3
				44	help
				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.
				51
				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.
				55
				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
				59	ACL protocol.
				60
				61	If unsure, say N.
