Last I checked, it worked like this:
If there's a /dev/console in initramfs, stdin, stdout, and stderr will
point to that. If you select no initramfs, you get one with just
/dev/console. If you create your own initramfs and don't put
/dev/console in it, init gets no file descriptors and there's a line
about it in dmesg.
