How the Zones Delegated Restarter Works

Each SMF service instance is managed by a restarter. The restarter retrieves instance configuration and provides an execution environment. See the smf_restarter(7) man page for information common to all restarters.

A zone SMF instance with the FMRI svc:/system/zones/zone:zonename is created by an install, attach, or clone zone operation. The zone SMF instance is removed from the system upon uninstall and detach zone operations.

Upon startup, the zones delegated restarter creates a zone SMF instance for any non-global zone that requires an SMF instance. If there is an existing zone SMF instance for a zone but it is in a state lesser than the instance configured, the restarter will remove the existing SMF instance.

The zones delegated restarter sets up the infrastructure necessary for each zone. The restarter performs the following steps when started:

• Initiates a zoneadmd daemon for each zone, restarting it when necessary. There will be a running zoneadmd for each zone that is in a state greater than configured.

• Runs the zoneadm boot command for all zones in the state installed, and runs the zoneadm attach command for all zones in the state unavailable. For more information, see the zoneadm(8) man page.

A zones delegated restarter provides the script in the zones service methods. The zones delegated restarter will be running under the existing zones service FMRI.
