During my experiments and edge cases yesterday I discovered that
Butterfly will boot from a Parrot build. All that needs to be done is to
change the vendor and model strings in menuconfig.
I've a vague notion that someone mentioned to me that Parrot and
Butterfly are pretty much identical, and that the Butterfly code is old,
smelly, and probably doesn't work. I've also an idea that was Stefan. I
could equally have made all that up, but thank you Stefan if not, and I
apologise for forgetting your advice!
