But you can't.. init= takes a single path to the binary to use, no

Anybody see an obvious way to make /dev/console a controlling TTY?
The user-space process who wants it as a controlling tty needs to run
ioctl(0, TIOCSCTTY, (void *) 1);
You should also take care to set up the termios parameters correctly.
