use of the macro in sbin/mount*'s, by replacing:
mopts[] = {
MOPT_STDOPTS,
{ NULL }
}
With:
mopts[] = {
MOPT_STDOPTS,
MOPT_NULL
}
This change will help to reduce the situation that we don't explicitly
initialize "struct mntopt"'s. It should not contribute to any
functional/logical changes as far as I can tell.
This unbreaks "/rescue/mount -t foo" -- previously it was necessary to
explicitly call "/rescue/mount_foo".

libufs, which only works for Charlie root.
This change reverts the introduction of libufs and moves the
check into the kernel. Since the f_fstypename is the same
for both ufs and ufs2, we check fs_magic for presence of
ufs2 and copy "ufs2" explicitly instead.

MAC support on the file system, if supported, which causes MAC to treat
each object as having its own label, rather than using a single label
for all objects on the file system. This doesn't have to be used in
combination with the tunefs/newfs flags -- it's an alternative.
in those cases:
1. File system was mounted by an unprivileged user.
2. File system was mounted by an unprivileged root user.
3. File system was mounted by a privileged non-root user.
Point 1 is when file system was mounted by unprivileged user
(sysctl vfs.usermount was equal to 1 then).
Point 2 is when file system was mounted by root, while sysctl
security.bsd.suser_enabled is set to 0 and sysctl vfs.usermount
is set to 1.
Point 3 is because we want to be ready for capabilities.

is all zeros. The kernel now consistently zeroes FSIDs for non-root
users, so there's no point in printing these.
Also fix a number of compiler warnings, including two real bugs:
- a bracket placement bug caused `mount -t ufs localhost:/foo /mnt'
to override the `-t ufs' specification and use mount_nfs.
- an unitialised variable was used instead of _PATH_SYSPATH when
warning that the mount_* program cound not be found.

ID for each file system in addition to the normal information.
In umount(8), accept filesystem IDs as well as the usual device and
path names. This makes it possible to unambiguously specify which
file system is to be unmounted even when two or more file systems
share the same device and mountpoint names (e.g. NFS mounts from
the same export into different chroots).

remove all the code which was trying to do so.
This code was nasty in several ways, it was hiding
the kernel bug where the kernel was unable to properly
load a module, and it was quitting if it wasn't able
to load the module. The consequence is that an ABI
breakage of the vfsconf API would have broken *every*
mount utility.
kernel access control.
Teach mount(8) to understand the MNT_MULTILABEL flag, which is used
to determine whether a file system operates with individual per-vnode
labels, or treats the entire file system as a single object with a
single (mount) label. The behavior here will probably evolve some
now that nmount(2) is available and can more flexibly support mount
options.
