7270230e88 o s/softupdates/it/ to reduce over-use of 'softupdates' in a single 
paragraph.

b2e2e310fd o Softupdates is now enabled by default on non-root file systems. Update 
language about softupdates to reference this fact, as well as slightly
  moderate the "recommend Softupdates for use on all filesystems" to
  "most filesystems" so as to be consistent with what sysinstall selects.

60114b8024 o Most users will use sysinstall(8) for partition layout, rather than 
disklabel(8), so add a reference to sysinstall(8).

07f4b9740e o Refer to hw.ata.wc as a 'loader tunable' rather than a 'kernel variable' 
for consistency with the rest of the document.  Since we've already
  described the properties of loader tunables elsewhere, remove the
  duplicate description of it being a boot-time property.

d888f91feb o Update tuning(7) to reflect auto-tuning of kern.maxusers in recent 
versions of FreeBSD.  This should be merged before 4.5-RELEASE, as this
  functionality is present in 4.5-RELEASE.

3626f83327 Update the default newfs block and fragment sizes from 8192/1024 to 
16384/2048.

Following recent discussions on the -arch mailing list, involving dillon
and mckusick, this change parallels the one made over a decade ago when
the default was bumped up from 4096/512.

This should provide significant performance improvements for most
folks, less significant performance losses for a few folks and
wasted space lost to large fragments for many folks.

For discussion, please see the following thread in the -arch archive:

Subject: Using a larger block size on large filesystems

The discussion ceases to be relevant when the issue of partitioning
schemes is raised.

98181c4975 o Reflect changed default such that keepalives are always enabled by 
default now.  Discuss why that's good.  Note that there are still
  some situations where turning it off may be advantageous, including
  situations where there are network outages and it's desirable to
  have TCP sessions last beyond the outage.

9aa92d5586 Moderate the recommendation that TCP keepalives always be turned on; 
in some environments, this may result in the early termination of
legitimate TCP sessions during temporary network outages.  However,
maintain a strong recommendation that this be used when many network
clients are dialup.

c1f3e4bf21 Removed whitespace at end-of-line; no content changes. I simply did 
cd src/share; find man[1-9] -type f|xargs perl -pi -e 's/[ \t]+$//'

BTW, what editors are the culprits? I'm using vim and it shows
me whitespace at EOL in troff files with a thick blue block...
