If I boot with init=/bin/bash and mount /proc so I can see what's happening, bash is called "init" and it is pid 1 as expected.
If I attempt to kill it, nothing happens because, by default, the kernel will not send a signal 9 to pid 1. However, I can exit and be left with nothing. In other words, if init exits, the kernel doesn't automatically start another.
I think anybody who is interested in what happends to init with signals can play with init=/bin/bash and get a good idea of what the behavior is. I don't know if it's the correct behavior. I always thought that init was even protected from exit(), but not so. Also, when booting with bash, one can `exec /sbin/init` and init will start normally --- with pid == 1 --- good(tm).
