No. The boot loader works. The scripts contained within the initrd (that
would probe devices for the live filesystem) have not yet run at this point.

I understand that the kernel makes a best effort to do this, but if
things go *really* wrong, recovery may be impossible. For a kernel
design more radically committed to this ideal, see GNU Hurd.
