--------------------------------------------------Script Ends 
Here-------------------------------------------------------

Now this script is specifically from Raspberry Pi because if you check 
in the end of script we are using Raspberry Kernel. According to me that 
is where you need to use Beaglebone kernel.
I am not sure whether you have any knowledge of debootstrap and kernel 
compilation, I would still like you to understand script rather than 
just just executing and creating debootstrap. Going through script will 
also give you overall understanding of core creation.

Let me know if you have any questions.
