What exactly do you mean by "image file system binary"? The ramdisk
image in ppc64/images/ramdisk_image.gz ?

Hm... then this is NOT the image ditributed with the ELDK. Here we
have:

	-> ls -l
	total 16
	drwxr-xr-x 2 1543 1543 3072 Apr  1 13:11 bin
	drwxr-xr-x 2 root root 3072 Apr  1 13:11 dev
	drwxr-xr-x 5 1543 1543 1024 Apr  1 13:11 etc
	drwxr-xr-x 2 1543 1543 1024 Apr  1 13:11 ftp
	drwxr-xr-x 2 1543 1543 1024 Apr  1 13:11 home
	drwxr-xr-x 2 1543 1543 1024 Apr  1 13:11 lib
	drwx------ 3 1543 1543 1024 Apr  1 13:11 lib64
	lrwxrwxrwx 1 1543 1543   14 Apr  1 13:11 linuxrc -> ../bin/busybox
	drwxr-xr-x 2 1543 1543 1024 Apr  1 13:11 proc
	drwxr-xr-x 2 1543 1543 1024 Apr  1 13:11 sbin
	drwxr-xr-x 2 1543 1543 1024 Apr  1 13:11 tmp
	drwxr-xr-x 4 1543 1543 1024 Apr  1 13:11 usr
	drwxr-xr-x 4 1543 1543 1024 Apr  1 13:11 var

This looks clean to me.

Why didn't you simply try the kenrel that comes included with the
ELDK?

Usually it is a good idea to try out such images by installing the
files in a directory tree and trying to chroot into it.
