a 3.4-STABLE and 5.0-CURRENT box

>Description:


I'm sick of people cp /etc/defaults/rc.conf /etc/rc.conf and
complaining about being out of file descriptors during boot.
This will let people do that silly thing, and it will stop
them from trashing their box.

>How-To-Repeat:

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

>Fix:
	


Here's a patch against v1.53 of rc.conf . It might
be a good idea to insert an echo or two to give the
user a big warning.
