And if I kill -9 (SIGKILL) the higher-numbered PID at test purpose, is it expected to reboot or not ? I see in code : case SIGCHLD: case SIGILL: case SIGFPE: case SIGSEGV: case SIGBUS: setup_signal(i, SIG_DFL); break; default: setup_signal(i, signal_handler); but can't conclude for a SIGKILL on higher-numbered PID process ...
