rc.conf patch

[chuck yerkes <chuck_(_at_)_snew_(_dot_)_com>]

Minor patch humbly submitted hopefully to get into 2.7.

WHAT:
rc.conf.local is sourced after rc.conf so that values in
the system supplied rc.conf can be overridden.

If a rc.conf.local does not exist, it will not be used.


WHY:
  So that I don't have to handle merging the -current
rc.conf everytime it changes, I've taken to using
the FreeBSD rc.conf.local method.
  With this, I know that rc.conf is unchanged by me and
I can track my differences easily and quickly.

DRAWBACKS:
  New variables will not automatically be noticed,
but then, you're going to use the default values
until you actually change them, so what's the diff.
