I think that this way linuxrc process does not die, so that root is not
changed

=== main.c
pid = kernel_thread(do_linuxrc, "/linuxrc", SIGCHLD);
        if (pid>0)
            while (pid != wait(&i));        <===========
        if (MAJOR(real_root_dev) != RAMDISK_MAJOR
             || MINOR(real_root_dev) != 0) {
#ifdef CONFIG_BLK_DEV_MD
            autodetect_raid();
#endif
            error = change_root(real_root_dev,"/initrd");
            if (error)
                printk(KERN_ERR "Change root to /initrd: "
                    "error %d\n",error);
        }
===

What happens if you take out the "exec" and leave linuxrc die?
