[c-nsp] Bootstrapping issue on sup720/6504

[Hyunseog Ryu]

It depends on inter-operability between two platforms - the platform, 
which was formatted, and the platform, which will be used.
But there is a great risk that the router may not boot from production 
network.
Why should you risk for it?
I had several situations that the router didn't recognize the IOS image 
during the boot while it is not formatted from same platform.
I guess it's up to you.

P.S. In some platform, if you have invalid IOS image in flash memory as 
first file readable, it may not work, too.
For an example, if you have text file before IOS image in flash 
disk/memory, it may not work.
