During the startup, more precisely, when init is started,
it does have stdin/out/err - it is passed to it by kernel
as three open descriptors, and all three are open to /dev/console.

Whether you see the output depends on where your /dev/console
is attached to.

Ctrl-C can interrupt only if the terminal you sent it from
is a controlling tty. /dev/console cannot be a controlling tty
by design, kernel enforcec that.
