Service Management Facility and Booting

SMF provides an infrastructure that augments the traditional UNIX startup scripts, init run levels, and configuration files. With the introduction of SMF, the boot process creates fewer messages now. Services do not display a message by default when they are started. All of the information that was provided by the boot messages can now be found in a log file for each service that is in /var/svc/log. You can use the svcs command to help diagnose boot problems. To generate a message when each service is started during the boot process, use the -v option with the boot command.

When a system is being booted you can select the milestone to boot to or select the level of error messages to be recorded. For instance:

Changes in Boot Behavior When Using SMF

Most of the features that are provided by SMF occur behind the scenes, so users are not typically aware of these features. Other features are accessed by new commands.

Here is a list of the behavior changes that are most visible:
