6757 * When an instance is imported we end up telling configd about it. Once we tell
6758 * configd about these changes, startd eventually notices. If this is a new
6759 * instance, the manifest may not specify the SCF_PG_RESTARTER (restarter)
6760 * property group. However, many of the other tools expect that this property
6761 * group exists and has certain values.
6762 *
6763 * These values are added asynchronously by startd. We should not return from
6764 * this routine until we can verify that the property group we need is there.
6765 *
6766 * Before we go ahead and verify this, we have to ask ourselves an important
6767 * question: Is the early manifest service currently running? Because if it is
6768 * running and it has invoked us, then the service will never get a restarter
6769 * property because svc.startd is blocked on EMI finishing before it lets itself
6770 * fully connect to svc.configd. Of course, this means that this race condition
6771 * is in fact impossible to 100% eliminate.
6772 *
6773 * svc.startd makes sure that EMI only runs once and has succeeded by checking
6774 * the state of the EMI instance. If it is online it bails out and makes sure
6775 * that it doesn't run again. In this case, we're going to do something similar,
6776 * only if the state is online, then we're going to actually verify. EMI always
6777 * has to be present, but it can be explicitly disabled to reduce the amount of
6778 * damage it can cause. If EMI has been disabled then we no longer have to worry
6779 * about the implicit race condition and can go ahead and check things. If EMI
6780 * is in some state that isn't online or disabled and isn't runinng, then we
6781 * assume that things are rather bad and we're not going to get in your way,
6782 * even if the rest of SMF does.
