General :: Initramfs - Attempted To Kill Init ?

For a special purpose I needed a initramfs - that didn't work. So I reduced the initramfs setup to the simplest.

Mount the root and switch_root into it. But that didn't work either.

If I go with the init-script for the initramfs I posted below the system prints out the switch_root usage-text from busybox. But the syntax is right, ain't it?

When I use chroot instead of switch_root then it prints the usage-text of init before the kernel panic.

If I try with "/sbin/init 5" then, after a while the system reports "init: timeout opening/writing control channel /dev/initctl".

In the other cases I get the following error messages before the system hangs: "Kernel Panic", "Attempted to kill init", "init not tainted"

(With the init script below there is a error saying:"sh: can't access tty; job control turned off". I know why it's there - but don't know if it is connected to this problem.)

This information may be important:
- The machine boots from a usb-harddisk
- /sbin/init on the new root is available
- the system on newroot is sane and runs perfect standalone (without initramfs)
- the system on newroot uses baselayout-2 with openrc
- busybox is built as static binary
- busybox version is v1.15.3

Here is the relevant data:
