Process #1 doesn't receive signals unless it installed a handler for
them. This means blocking signals around the fork intended to confuse
what the main operation of the program in question happens to be (reap
orphaned processes) is useless.

The setpgid(0, 0) does nothing because setsid already put the process
into its own process group.

A minimal variant of that which is less contorted and actually a valid C
program could look like this:

----
#include <unistd.h>
#include <sys/wait.h>

int main(void)
{
    if (getpid() != 1) return 1;

    if (fork() == 0) {
    setsid();
    execve("/etc/rc", (char *[]){ "rc", 0 }, (char *[]){ 0 });
    }

    while (1) wait(NULL);

    return 0;
}
----

But don't let that deter from assuming that whoever screams the loudest
must be the greated ...
