>Description:
	Putting unbound=YES in rc.conf makes it run (chrooted by
	default), but makes syslogd not start on next boot. The
	reason for that is that it thinks it should create a socket
	for unbound in /var/chroot/unbound/var/run/, which does
	not exist. It appears unbound opens /var/run/log before
	chrooting, so the socket in its chroot and the directory
	are not actually needed.
>How-To-Repeat:
	echo unbound=YES >>/etc/rc.conf
	/etc/rc.d/syslogd restart
>Fix:
	The following is a possible fix.
