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.

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.

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).

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.

an IPv6 address containing ':', one must use the '@' separator for it
to be properly parsed (mount_nfs(8) still needs fixing at the moment
though).

enough. The bit may be reset later if, say, the filesystem is marked `ro'
in fstab. The command line option should override the fstab setting, but
did not. The implementation of -r was changed for consistency.

Changes are:
- rpc.umntall is called at the right places now in /etc/rc*
- rpc.umntall timeout has been lowered from two days (too high) to one
- verbose messages in rpc.umntall have been clarified
- kill double entries in /var/db/mounttab when rpc.umntall is invoked
- ${early_nfs_mounts} has been removed from /etc/rc
- patched mount(8) -p to print different pass/dump values for ufs filesystems.

1. Get rid of the evilly bogus strdup(fstab) and free if (fstab == "")
as in umount.
2. Don't use /etc/fstab info if the mount instance does not exactly match
the fstab entry.
3. Reversed the mountpoint checking order in getmntpt().
4. Clarify the "not mounted" error message in mount -u. The previous
"unknown special file or file system" wasn't quite right.
5. Get rid of a 1-byte memory leak; this was reported by jhb.

Made mount more userfriendly (bad slashes are now filtered out)
and we remove in mount_nfs trailing slashes if there are any.
Fixed mount_xxx binarys to resolve with realpath(3)
the mountpoint.
Translate the deprecated nfs-syntax with '@' to ':' .
The ':' syntax has now precedence, but '@' still works.
Notify the user that the '@' syntax should not be used.

-o fstab brings in filesystem options specified in /etc/fstab
-o current incorporates the current set of options for the file

The rightmost option wins in the case of conflicting options being
specified.
E.g.:-
# mount -u -o current,nosuid /home

Add an option to the way UFS works dependent on the SUID bit of directories
This changes makes things a whole lot simpler on systems running as
fileservers for PCs and MACS. to enable the new code you must
1/ enable option SUIDDIR on the kernel.
2/ mount the filesystem with option suiddir.
hopefully this makes it difficult enough for people to
do this accidentally.
see the new chmod(2) man page for detailed info.
