0af9d56f46 In this GRN, Marcel Moolenaar overhauled the logic for mounting
the root file system on bootup:

   |------------------------------------------------------------------------
   |r214006 | marcel | 2010-10-17 22:01:53 -0700 (Sun, 17 Oct 2010) | 20 lines
   |
   | Re-implement the root mount logic using a recursive approach, whereby each
   |root file system (starting with devfs and a synthesized configuration) can
   |contain directives for mounting another file system as root.
   |------------------------------------------------------------------------

This commit adds a mount.conf(8) man page which documents
the root mount logic.  mount.conf(8) also provides some examples
for the /.mount.conf file, which can be used to change the root mount behavior.

The "failok" option doesn't have any effect at all unless specified in
fstab(5) and combined with the -a flag. The "failok" option is already
documented in fstab(5).

65d8b7120d Disconnect non-MPSAFE SMBFS from the build in preparation for dropping
GIANT from VFS. In addition, disconnect also netsmb, which is a base
requirement for SMBFS.

In the while SMBFS regular users can use FUSE interface and smbnetfs
port to work with their SMBFS partitions.

Also, there are ongoing efforts by vendor to support in-kernel smbfs,
so there are good chances that it will get relinked once properly locked.

This is not targeted for MFC.

85c1a64cec Disconnect non-MPSAFE NTFS from the build in preparation for dropping
GIANT from VFS. This code is particulary broken and fragile and other
in-kernel implementations around, found in other operating systems,
don't really seem clean and solid enough to be imported at all.
If someone wants to reconsider in-kernel NTFS implementation for
inclusion again, a fair effort for completely fixing and cleaning it
up is expected.

In the while NTFS regular users can use FUSE interface and ntfs-3g
port to work with their NTFS partitions.

In the possibility of a future maintenance of the code and later
readd to the FreeBSD base, maybe we should think about a better location
for netncp. I'm not entirely sure the / top location is actually right,
however I will let network people to comment on that more specifically.

66b402e198 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.
Discussed on freebsd-fs@.

2ef52c99e0 As statfs.f_flags are uint64_t the local variables should be as well.
We'll start noticing this with the next flag introduced as the lower
32bit are all used.
As this is old code we might need to do a full tree sweep one day, unless
changing our strategy to use a different `API' for getting/setting flags
along with the rest of the statfs data.

While here compare to 0 explicitly [1].

bfed6ac3d6 Add a -o mountprog parameter to mount which explicitly allows
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
