under the SMF datalink/interface networking model we've been discussing here and elsewhere, SMF instances will exist for datalinks and IP interfaces. one problem with this is that the policy engine handling such instances, e.g. NWAM, would like to receive notifications of adminstrator-driven events such as disabling the instance or refreshing, while not taking full responsibility for managing the instance (as a delegated restarter would - NWAM can't be a delegated restarter since the datalink/IP interface instances exist whether NWAM is enabled or not).
one approach would be to use (and of course a contract would be needed for this) the private libscf property group notification function _scf_notify_add_pgname(), specifying we want notifications for the SCF_PG_GENERAL, SCF_PG_GENERAL_OVR and SCF_PG_RESTARTER_ACTIONS property groups. placing notifications on the first two catches enable and disable events, persistent and temporary. notifications for SCF_PG_RESTARTER_ACTIONS catch refresh, restart, maintenance, clear events. we can then use _scf_notify_wait(), fish out the FMRI and handle the event. does this approach have drawbacks? is there a better way to catch such events? thanks! alan
