Explanation:
E:
* Many configuration tasks around name services have moved into the SMF in Solaris 11.
*The Service Management Facility (SMF), first introduced in Oracle Solaris 10, is a feature of the
operating system for managing system and application services, and it replaces the legacy init
scripting start-up mechanism common to prior releases of Oracle Solaris and other UNIX
operating systems. SMF improves the availability of a system by ensuring that essential system
and application services run continuously even in the event of any hardware or software failures.
SMF is one of the components of the wider Oracle Solaris Predictive Self Healing capability.
Note:
*In Oracle Solaris 11, certain aspects of system configuration have changed, including the
migration of several system, network, and naming services configuration to SMF.
