The answer is yes, however, it is policy driven. Users will have numerous 'derived' types that are less privilege than, for example, their interactive shell. For example, user_irc_t or user_evolution_t. The transitions will happen when the user runs irc or evolution and those apps will be limited to the rights they require. These are fine grained though, and mandatory. These capabilities are so course grained I just can't see anyone ever using them. - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
