True, but overwriting the MAC shouldn't be something a customer does on 
accident. This is why I think it makes more sense to bind the MAC into a 
protected bootloader.

If your building an application specific board, where the OS is probably not 
going to be modified once it's in the field, then it probably doesn't matter.
But if you building a generic board, then embedding the MAC into the OS is 
making it difficult for the customers to change OS's, or upgrade.

If the customer is using the bootloader for reflashing their OS, (which is 
safer and cheaper) then they don't have to worry about accidentally 
overwriting the MAC. 

my two cents.
NZG.
