It actually has to do with the way tty process groups are created and
signals are managed. If you boot _any_ Linux kernel using something
like 'init=/bin/sh', ctl-C doesn't work because the process in slot 1
(normally init) is treated with special signal handling by the kernel.

Huh? All you need to do is properly start up an interactive
session from init to get process group signal handling. This is
just standard Linux userland stuff documented in a variety of places.
