85148c25cf Remove, with extreme prejudice, the notion that /tmp best needs to be a 
softlink to /var/tmp.

This is horribly wrong since /tmp and /var/tmp serve different goals.
Even given the text that in the old days things were different doesn't help,
since our scripts clean /tmp, and we depend on /var/tmp to persist for
vi editing sessions recovery and other likewise applications.

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.

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.

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...
