you cannot mount loopback fs's from a ramdisk. copy it to a real partition then try to mount it.
I was unable to mount the iso image via loop device
example
dd if=/dev/zero of=/ramdisk/test.iso bs=1024k count-20
mke2fs -b 2048 /ramdisk/test.iso
(press y for continue)
mkdir /test
mount -o loop /tmp/test.iso /test
(it gives error as ioctl: LOOP_SET_FD invalid argument)
so please advice me is there any other way to mount the iso file

So how is it possible that the kernel on the knoppix CD can do it from tmpfs (/ramdisk).Originally Posted by eadz
It does a loopback mount when it creates the image for the terminal-server on line 230 in /etc/init.d/knoppix-terminalserver
When I use my own kernel it doesn't work, so anyone an idea what other patches knoppix uses to make this work?
I sorted out this problem, when you copy the iso image to /ramdisk it doesn't work and it will work if you copy the iso image to /, but yiu need to rebuild the initrd.gz with more space
FYI
I've found the solution .. knoppix uses loop-aes which seems to work on tmpfs

I've used that module and now I can loopback mount images
