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.
Discussed on freebsd-fs@.

The default NFS client is now the new NFS client, so 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, it is recommended that the mount(8) and mount_nfs(8)
commands be rebuilt from sources and that a link to mount_nfs called
mount_oldnfs be created. The new client is compiled into the
kernel with "options NFSCL" and this is needed for diskless root
file systems. The GENERIC kernel configs have been changed to use
NFSCL and NFSD (the new server) instead of NFSCLIENT and NFSSERVER.
To use the regular/old client, you can "mount -t oldnfs ...". For
a diskless root file system, you must also include a line like:
vfs.root.mountfrom="oldnfs:"
in the boot/loader.conf on the root fs on the NFS server to make
a diskless root fs use the old client.
