If the get_boot_id() is accepted by the random folks, then I'm fine with this change.Yeah, BTW, Sashiko found this can be initialized before we get enough entropy for random seed. Maybe we need one more delay.
Well, maybe for adding the boot_id later, but the code that initializes the buffers needs to stay early. With the backup instance, the persistent ring buffer can restart tracing immediately. -- Steve
