Creating more than 8 loop back devices in Linux

By default Linux  supports only 8 loop back devices which means we can mount maximum 8 loop back devices(for Eg: 8 iso images)and maximum supported loop back devices by OS is 64.  If you tried to mount the 9 th devices, you may get an error "mount could not find a spare loop device" error.  Below script create the loop back devices from 8 to 64 

for ((i=8;i<64;i++)); do
[ -e /dev/loop$i ] || mknod -m 0600 /dev/loop$i b 7 $i
done

Enjoy.... Now you can mount up to 64
