bind problem

[flourishing]

i installed bind-chroot ,but the file /etc/named.conf always is

options {
pid-file "/var/run/named/named.pid";
directory "/var/named";
auth-nxdomain no;
/*
* If there is a firewall between you and nameservers you want
* to talk to, you might need to uncomment the query-source
* directive below. Previous versions of BIND always asked
* questions using port 53, but BIND 8.1 uses an unprivileged
* port by default.
*/
// query-source address * port 53;
};
the red part. even i change that to /var/named/chroot ....
and copied /var/named/name.* pr* /var/named/chroot/var/named/
when restart the named.conf change to orignal. set the directory to /var/named
and the ispconfig dns manager auto create the pri-file in the directory /var/named

what should i do?
i am just wondering . the same install sequence ,why this time the bind-chroot can't work fine.

Change the config template of the named.conf in /root/ispconfig/isp/conf

You can set the named directory in ISPConfig: Management -> Server -> Settings -> DNS.
