[CentOS] webmin and DNS configuration on CentOS 6.2

>I have two seemingly identical (in this reglard, at least) machine - both

>webmin to edit the DNS configuration. One one of them it seems to work
>fine, on the other I get messages akin to the following:
>Failed to create master zone : Failed to replace
>/var/named/chroot/etc/named.conf with
>/var/named/chroot/etc/named.conf.webmintmp.13214 : Device or resource busy

>From that page: "The best fix for now would be to 
stop using the chroot completely, as it has few real security benefits 
in my opinion."
