55e50ace1e Implemented user side of "noatime" mount option. This option disables
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).

a257a45ecd I have added a new option -p to the mount command. This was
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]

b6cf6bb275 Change the messages slightly when there is no "mount_type" executable
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 ", ").

d5f6aa5f24 Backout my changes to disallow "mount /mnt /mnt" until I can verify
that nfs mounts work again (I locked up my home machine testing it and can't
see what happened until I get home from work tonight).

bd70de3eaf Only restrict the user from doing something like "mount /mnt /mnt"
for file system types that actually cause a panic (ufs, msdos, cd9660).
This makes /proc mountable again.

d48b626da3 Do not allow the caller to specify the same path for the special
device file and the mount point.  This prevents the "unexpected recursive
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).

66fa281751 Close PR#17. This may be a contraversal fix in that now mount will
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.

89beb278f7 The changes for adding the "noauto" option were mostly wrong. MNT_NOAUTO
is a kernel flag, and the kernel definately doesn't need to know about
it.

81b9534dc5 Add a "noauto" flag so that you can do things like prevent your system
from not coming up multiuser just because you have a CD mount in fstab
but no CD in the drive.

8a978495e7 Verify that the last component of the mount point path exists and is
a directory - allows for better error reporting.

c974f9c6a6 Use getvfs* functions to map between VFS types and names.
Automatically load UFS if it is not present but is loadable.
(This won't happen now, but could happen if we fix NFS diskless support.)
