#139 Feature: Heads bios optional functionality

Nitrokey has something similar, would be nice to have such functionality.

I would have said otherwise, but Hyperbola's implementation of HyperbolaBSD is required before they will have Hyperboot built. They removed it for now from roadmap in order to not overpromise.

Just a suggestion, do with it what you like.

already working on my own flash distro, i'll simply release when ready

Was unaware of this, hmm... okay.
