svn commit: r197697 - in head/etc: . rc.d

[Hiroki Sato]

Author: hrs
Date: Fri Oct  2 02:24:25 2009
New Revision: 197697
URL: http://svn.freebsd.org/changeset/base/197697

Log:
  - Add AF_IPX and AF_NATM to afexists().
  
  - Add afexists() check to address family specific rc.d scripts.  A
    script for an AF will be silently ignored if the kernel has no
    support for the AF.
