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.
