Solaris Naming Administration Guide

The named.boot File

The boot file (/etc/named.boot) establishes the server as a primary, secondary, or cache-only name server. It also specifies the zones over which the server has authority and which data files it should read to get its initial data.

The boot file is read by in.named when the daemon is started by the server's start up script, /etc/init.d/inetsvc. The boot file directs in.named either to other servers or to local data files for a specified domain.)
