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.

the filesystem type isn't given in the command line. In the case of
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).

least in -w's case, simply unsetting the correct bit in init_flags was not
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.

options:
-o fstab brings in filesystem options specified in /etc/fstab
-o current incorporates the current set of options for the file
system
The rightmost option wins in the case of conflicting options being
specified.
E.g.:-
# mount -u -o current,nosuid /home
will preserve the current mount options while adding the 'nosuid' flag.

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.

filesystem overhead in cases where the access time is not important (like
Usenet news spools).
inspired by SunOS version of mount which uses option -p to
indicate that the mount information should be printed in fstab
format.
This is a neat way to create a new fstab file to use later when
one has modified the mount points or mount options or added or
removed mount some mount points. You just type
mount -p > /etc/fstab.new
and there is your new fstab file ready to be used though you
will of course have to add any necessary noauto flags manually.
[Committers note: This also seems to do the wrong thing for AMD
mounts, but in the more average case this is a nifty feature nonetheless
and one can always edit the bogus entries out]

found when the user specifies "mount -t type". Instead of printing
out one message for each path element (/sbin, /usr/sbin), it prints
out:
mount: exec mount_type not found in /sbin, /usr/sbin: No such file or directory
The code is quite long for such a stupid little piece of aesthesism
but it is very straghtforward so I guess it's ok. Besides, I don't
want to do a "char foo[100];" and have malloc break down when someone
decides to add a few more paths to a variable that's far apart from
this code. :)
By the way, there is no malloc() off-by-one error for the '\0' at the
end of the string although I don't explicitly add 1 to the length.
The code allocates strlen(path element)+2 bytes for each path element,
and doesn't use the last two bytes (for the delimiting ", ").

lock" panic from happening.
This is a temporary fix. A kernel fix would be much much more ugly than
this, and still wouldn't be the "right" way to fix it. After some
of Terry's file system rework is installed, it will be possible to
properly fix this problem in a clean manner. Until then,
this change should prevent use from getting a problem report
on this every month or so (and I just noticed that someone in
one of the freebsd news groups was complaining about this problem, too).
spit out two error lines for a bogus filesystem type, e.g:
root@time-> mount -t foo /dev/sd0a /mnt
mount: exec /sbin/mount_foo for /mnt: No such file or directory
mount: exec /usr/sbin/mount_foo for /mnt: No such file or directory
But I would submit that if you're even going to scan multiple directories
for a mount_foo (which I actually think is somewhat bogus - if it's not
in /sbin, you're probably in big trouble anyway), you should emit an error
for each one. I got multiple complaints (in addition to the PR) that the
existing behavior was very confusing.
