Ok.  Something like this:
    for (;;) {
	...
  
	if (pid1 == 0 && tty0_commands) {
            pid1 = run(tty0_commands, console, wait_for_enter);
        }

	...
 
        if (wpid == pid1) {
            if (run_rc == FALSE) {
                pid1 = 0;
            }
            else {
                run_rc=FALSE;
                wait_for_enter=TRUE;
    #ifdef DBOOTSTRAP
                tty0_commands= { "dbootstrap", "dbootstrap" 0};
    #else
                tty0_commands=shell_commands;
    #endif
            }
        }

	...

	sleep(1);
    }
? so that the first time around we run the rc script,
but all subsequent time around the loop we run dbootstrap?
