I am trying to run bind9 with chroot jail. I followed the steps mentioned at : http://www.howtoforge.com/debian_bind9_master_slave_system

I am getting the following errors in my syslog:

Looks like the process can not read the file /var/lib/named/etc/bind/named.conf. I have made sure that the owner of this file is user bind, and it has the read/write access to it:

What could be wrong here?
