Manually created configuration might not work correctly with the *named-chroot* service after upgrading
When you use the the *named-chroot* service and when you have your own manually created configuration files in the `/var/named/chroot/` directory, the service might not work properly on the target system after the upgrade to Red Hat Enterprise Linux 7. The `options` section in the used configuration files must contain the `session-keyfile` and `pid-file` directives, such as in the following example:
The *Preupgrade Assistant* modules do not check or fix the manually created files in the `/var/named/chroot/` directory. To work around this problem, manually insert the lines above to the `options` section. If you do not have your own manually created configuration files in `/var/named/chroot/`, the configuration files of *bind*, including the `/etc/named.conf` file, are used. These configuration files are checked and fixed by the *Preupgrade Assistant* modules.
