Problem - busybox mount can not mount loopback image.
Standard mount make it on the same computer with the same image.
Michael.
P.S. I tried to perform above tasks in two stages, with losetup:
~> busybox losetup /dev/loop0 /var/tmp/ppc.img
~> echo $?
0
~> busybox mount -t cramfs /dev/loop0 /mnt
mount: Mounting /dev/loop0 on /mnt failed: Permission denied
~>
Regarding permission - I was working as root...
