Szwg Boottime Endpoint

Two dummy functions are inserted as follows;

static int init(void * unused) {   lock_kernel; do_basic_setup;

prepare_namespace;

/*    */    free_initmem; unlock_kernel; celf_sz_boottime_dummy;<<<<<<<<<<( Here
 * Ok, we have completed the initial bootup, and
 * we're essentially up and running. Get rid of the
 * initmem segments and start the user-mode stuff..

if (open("/dev/console", O_RDWR, 0) < 0) printk("Warning: unable to open an initial console.\n");

(void) dup(0); (void) dup(0);
