	I suspect that you are runing with "-t /chroot/named" and
	as such "/chroot/named" is *NOT* needed in the file references
	in named.conf.  Named is trying to open
	"/chroot/named/chroot/named/etc/tmp-XXXXWkiZFA" and
	"/chroot/named/chroot/named/etc" does not exist resulting in
	the error being reported.
