I have two seemingly identical (in this reglard, at least) machine - both of them are running CentOS 6.2 with bind (bind-chroot) installed. I used 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."
