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.

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.

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.
- use new getvfsbyname() interface and mount(2) interface
**DANGER WILL ROBINSON!!** You must be running a -current kernel
from within a week or so in order for this to work!
the file access time update on reads and can be useful in reducing
filesystem overhead in cases where the access time is not important (like
Usenet news spools).
from not coming up multiuser just because you have a CD mount in fstab
but no CD in the drive.

most common cd9660 and nfs options like God intended them. (It is now
possible to say
mount -o ro,soft,bg,intr there:/foo/bar /foo/bar
again.) This whole getmntopt() business is an incredible botch;
it never should have been anything more than a wrapper around
getsubopt(3). Because if the way the current hackaround is implemented,
options which take arguments (like the old `rsize' and `wsize') are still
unavailable, and must be accessed the new, broken way.
(It's unimaginable how Berkeley managed to screw up one of the few things
about NFS that Sun actually got right to begin with!)
