${named_chrootdir}/usr/libexec/named-xfer
${named_chrootdir}/dev/null
${named_chrootdir}/etc/localtime

/var/run/ndc -> ${named_chrootdir}/var/run/ndc

under $named_chrootdir as user named group named.
to take advantage of this, an admin should copy /etc/namedb ->
${named_chrootdir}/etc/namedb, and set named_chrootdir in /etc/rc.conf.
[dev/null & etc/localtime setup inspired by openbsd. i already had the rest]
