chroot

[Kevin Darcy]

Do you understand how chroot() works? Simply put, it makes all of your
pathnames relative to the chroot()'ed directory. So if named would normally
expect to find its configuration file at /etc/named.conf, if it is chroot()'ed
to /var/named it would expect to find the file at /var/named/etc/named.conf.
Any other pathname it uses will also need to be relative to the chroot()
directory.
