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.

As this is old code we might need to do a full tree sweep one day, unless

experimental client is used when the fstype is "newnfs" or the "nfsv4"
option is specified. It includes the addition of the option:
gssname - to specify a client side initiator host based principal name
which is specific to NFSv4.
It also includes a change to mount.c, so that it knows about
mount_newnfs, but not mount_nfs4.

an alternative program to be used for mounting a file system.
Ideally, all file systems
should be converted to pass string arguments to nmount(), so that
/sbin/mount can handle them. However, certain file systems such as FUSE have
not done this, and want to have their own userland mount programs.
For example, to mount an NTFS file system with the FUSE NTFS driver:
mount -t ntfs -o mountprog=/usr/local/bin/ntfs-3g /dev/acd0 /mnt
or via an fstab entry:
/dev/acd0 /mnt ntfs ro,noauto,mountprog=/usr/local/bin/ntfs-3g 0 0

no equivalent conversion happens in "umount -t", which led to some

For filesystems which use vfs_mount_error() to log an error, this

If nmount() fails, in addition to printing out strerror(errno),
print out the "errmsg" populated by vfs_mount_error().

This has been happening due to the priority inversion; options
specified on the command line should take precedence over options
from fstab over default "noro" option, but since both the default
"noro" and options specified on the command line (-w, -r, -o ...)
were put into the same "options" variable, "noro" took precedence
over fstab "ro" (this is easily visible with "mount -d").

Add an rc script, mountlate, which basically runs 'mount -a -l'. It runs
after DAEMON but before LOGIN.
This is useful for things like loopback mounts, because mountcritremote
runs before mountd / nfsd (since /usr might be a remote file system), so
an attempt to mount a loopback network file system in mountcritremote will
fail.
Also add a progress message to mountcritlocal, for the sake of symmetry
with similar messages in mountcritremote and mountlate.

When doing a mount update, this will implicitly pass a "noro" mount
option down to the VFS layer.
vfs_mergeopts() in vfs_mount.c will then remove the "ro" mount option
if it exists in the mount options for a mounted file system.
This means that "mount -u" works the same as "mount -u -w"
and will convert a read-only mount to read-write.
