Since 1.5.4, VDR forks into a child that does nothing but fork off a
second child, and do an exit(0). The second child exec's the shutdown
script:
VDR
+-- Child 1 -> exits
+-- Child 2 -> runs shutdown
That way the waitpid quickly returns, the second child becomes orphaned,
and no process ends up being a zombie.
Since the shutdown script runs orphaned, the return value of the script
is not evaluated, nor does anyone wait for the script to terminate.
Cheers,
Udo
