Hi,
once again. I just found out that I cannot shutdown with init. It complains:
init: must be run as PID 1
(which is correct).
But why is it not 1?

Did you not start it from the kernel, but perhaps from a shell script?
The first process the kernel starts is PID 1.

I have a look. Normally I start my kernel and thought the kernel keeps
track of the init process.
>> The first process the kernel starts is PID 1.
sure, but that normally is init. Don't know why it's not here.

You have to use "halt" or "poweroff". Busybox does not support runlevels so you
cannot run "init 0" to shutdown your system.

This message comes from the new spawned init process, which gets a "usual" pid
like any other process. There should already be an init process with the pid 1.
