[BusyBox] Busybox init with devfs, shmfs, and pivot_root

[Laurence Anderson]

I had exactly the same problem. The problem seems to be that linuxrc doesn't 
get PID 1, therefore neither does init. This is because of some kernel root 
swapper process, used to support the old linuxrc mechanism.

The way I solved it was to have the kernel command line:

linux init=/linuxrc root=/dev/ram0
