>Description:
Program file override in /etc/rc.conf stopped working in 8.0-STABLE due to this change in /etc/rc.subr:

original (7.2):
        eval _override_command=\$${name}_program
        command=${_override_command:-$command}

current (8.0):
        eval _override_command=\$${name}_program
        command=${command:-${_override_command}}

output from sh -x:
+ _rc_prefix=''
+ eval '_override_command=$named_program'
+ _override_command=/usr/local/sbin/named
+ command=/usr/sbin/named
+ _keywords='start stop restart rcvar reload'

/etc/rc.subr version:
# $NetBSD: rc.subr,v 1.67 2006/10/07 11:25:15 elad Exp $
# $FreeBSD: src/etc/rc.subr,v 1.88.2.6 2009/12/07 06:25:19 hrs Exp $

>How-To-Repeat:
set in /etc/rc.conf:
named_program="/usr/local/sbin/named"

/usr/sbin/named will be run!


>Fix:
backout the change (what was the reason?)
