addition, take out the checks on the $dumpdev. dumpon(8) behaves well
if given a non-existent filename. It gives a nice error message which
is better rather than the current silent failure.

load, and $ipfilter_active can be "YES" when we are not using ipf(8).

For a detailed description look at the commit log for sysctl.c
rev.1.42 -- i do not think it is appropriate to put the full
description in this manpage, and the "boot" and "loader" manpages
where this description might go are also missing a description of
a number of similar variables, so i think this it is ok to limit
documentation to this now, and update it later when I (or someone
else) have a chance to revise "boot" and "loader".
very large package is exactly the kind of thing that users buy the
CDs for, so leaving it off of a 4 CD set is very bad.
* Properly quote the last security/sudo entry.
* Add a comment in the CDROM #2 section explaining that packages don't
typically go on this disc.
The stat() and open() calls have been changed to make use of this new functionality. Using shared locks in
these cases is sufficient and can significantly reduce their latency if IO is pending to these vnodes. Also,
this reduces the number of exclusive locks that are floating around in the system, which helps reduce the
number of deadlocks that occur.
A new kernel option "LOOKUP_SHARED" has been added. It defaults to off so this patch can be turned on for
testing, and should eventually go away once it is proven to be stable. I have personally been running this
patch for over a year now, so it is believed to be fully stable.

SSH login failures. This is similar but not identical to a patch
submitted by aeonflux@synapse.subneural.net.
o Introduce /var/log/authentication.log, which will be the target for
auth.info and authpriv.info by default. Rotate on the same schedule
as most other logs. Create at installation.
o Remove logging of auth.info from /var/log/security.log, which will
return to being only for security feature subsystems (such as ipfw,
and so on).
This creates a special authentication log, which can now be searched
by scripts for authentication events.
update the free-space statistics in some cases. The problem affected
directory blocks when the free space dropped below the size of the
maximum allowed entry size. When this happened, the free-space
summary information could claim that there are no further blocks
that can fit a maximum-size entry, even if there are.
The effect of this bug is that the directory may be enlarged even
though there is space within the directory for the new entry. This
wastes disk space and has a negative impact on performance.
Fix it by correctly computing the dh_firstfree array index, adding
a helper macro for clarity. Put an extra sanity check into
ufsdirhash_checkblock() to detect the situation in future.

The trouble here is that we don't reopen the device in read/write mode
when we remount in read/write mode resulting in a filesystem sending
write requests to a device which was only opened read/only.
I'm not quite sure how such a reopen would best be done and defer
the problem to more agile hackers.
