SMF Master Restarter Daemon

The svc.startd daemon is the master process starter and restarter for the Solaris OS. The daemon is responsible for managing service dependencies for the entire system. The daemon takes on the previous responsibility that init held of starting the appropriate /etc/rc*.d scripts at the appropriate run levels. First, svc.startd retrieves the information in the service configuration repository. Next, the daemon starts services when their dependencies are met. The daemon is also responsible for restarting services that have failed and for shutting down services whose dependencies are no longer satisfied. The daemon keeps track of service state through an operating system view of availability through events such as process death.
