From 66b402e198b741aaef0494b904ca943e26928dcf Mon Sep 17 00:00:00 2001 From: rmacklem Date: Wed, 27 Apr 2011 17:51:51 +0000 Subject: This patch changes head so that the default NFS client is now the new NFS client (which I guess is no longer experimental). The fstype "newnfs" is now "nfs" and the regular/old NFS client is now fstype "oldnfs". Although mounts via fstype "nfs" will usually work without userland changes, an updated mount_nfs(8) binary is needed for kernels built with "options NFSCL" but not "options NFSCLIENT". Updated mount_nfs(8) and mount(8) binaries are needed to do mounts for fstype "oldnfs". The GENERIC kernel configs have been changed to use options NFSCL and NFSD (the new client and server) instead of NFSCLIENT and NFSSERVER. For kernels being used on diskless NFS root systems, "options NFSCL" must be in the kernel config.
