>Release:        FreeBSD 3.2-STABLE i386
>Organization:
KUBOTA Corp. Technology Development Headquarters, Tokyo Japan
>Environment:

	Tested with FreeBSD 3.2-STABLE, as of CTM's src-3.0273.gz, on a
	NEC VersaProNX.

>Description:

	System will fail to boot with ".: Out of file descriptors" error,
	if by accident, or by what ever reason, overwriting /etc/rc.conf
	with /etc/defaults/rc.conf.
        May be reproducable on -current too?

>How-To-Repeat:

	# cp /etc/defaults/rc.conf /etc/rc.conf
	# reboot

>Fix:
	
	Apply the following patch to etc/defaults/rc.conf, to prevent
	recursive includes of rc_conf_files.
