Ok.. so if you are using the init from Busybox, there should be a
softlink and I can't remember where they put it.  I think it is the
root file system.  I think they call in linuxrc or something like
that.  I'd make sure you have that.

**OR** what I did..

Get sysinit from GNU and tell Busybox not to use the init.  I've had
this exact same problem and it was my init.
