No, I use the init applet with busybox stable (.4) and when I execute
halt on x86 the kernel panics (I accidently wrote reboot panics, when
I replied to the first poster). 

Init
- catches the signal sent by halt like described above, 
- calls the reboot command to halt the system, 

The kernel 
- calls machine_halt() (which ist empty on x86)
- calls exit() in the context of init
- panics since it is not allowed to terminate init.

In this thread is a discussion comparing the busybox/sysv-init
behaviour and the result was, that the busybox behaviour is wrong and
Erik said he would accept patches implementing the correct
behaviour. Looks like nobody submitted a patch. Erik?
