4986 4987 * more than one mechanism in the system. In other cases, there

4988 4989 * system the privilege covers to allow its use within a
4989 4990 * non-global zone.
4990 4991 *
4991 4992 * Set of privileges required in order to get a zone booted and
4992 4993 * init(1M) started. These cannot be removed from the zone's
4993 4994 * privilege set.

4996 4997 * processes executing inside a non-global zone.

7131 7132 * The following three routines implement a simple locking mechanism to
7132 7133 * ensure that only one instance of zoneadm at a time is able to manipulate
7133 7134 * a given zone. The lock is built on top of an fcntl(2) lock of
7134 7135 * [<altroot>]/var/run/zones/<zonename>.zoneadm.lock. If a zoneadm instance
7135 7136 * can grab that lock, it is allowed to manipulate the zone.
7136 7137 *
7137 7138 * Since zoneadm may call external applications which in turn invoke
7138 7139 * zoneadm again, we introduce the notion of "lock inheritance". Any
7139 7140 * instance of zoneadm that has another instance in its ancestry is assumed
7140 7141 * to be acting on behalf of the original zoneadm, and is thus allowed to
7141 7142 * manipulate its zone.
7142 7143 *
7143 7144 * This inheritance is implemented via the _ZONEADM_LOCK_HELD environment
7144 7145 * variable. When zoneadm is granted a lock on its zone, this environment
7145 7146 * variable is set to 1. When it releases the lock, the variable is set to
7146 7147 * 0. Since a child process inherits its parent's environment, checking
7147 7148 * the state of this variable indicates whether or not any ancestor owns
7148 7149 * the lock.
