The /etc/sysconfig/named file is used to pass arguments to the named daemon at boot time. The named daemon is a Domain Name System (DNS) server which implements the Berkeley Internet Name Domain (BIND) version 9 distribution. This server maintains a table of which hostnames are associated with IP addresses on the network.
Currently, only the following values may be used:
ROOTDIR="</some/where>", where </some/where> refers to the full directory path of a configured chroot environment under which named runs. This chroot environment must first be configured. Type info chroot for more information.
OPTIONS="<value>", where <value> is any option listed in the man page for named except -t. In place of -t, use the ROOTDIR line above.
For more information about available parameters for this file, refer to the named man page. For detailed information on how to configure a BIND DNS server, refer to Chapter 12, Berkeley Internet Name Domain (BIND). By default, the file contains no parameters.
