If you don't change ownership and you do have slave zones in the
now-root-owned directory, it will break.  If you do change ownership,
you revert the security improvements.

It would be best to tweak named.conf to use the sub-directory, and
get your config files into the chroot (otherwise you have to edit
/etc/sysconfig/named to remove ROOTDIR).
