Short description

Flashing HEADS

We should at least bring up HEADS:

HEADS is an open source custom firmware and OS configuration for laptops and servers that aims to provide slightly better physical security and protection for data on the system. Unlike Tails, which aims to be a stateless OS that leaves no trace on the computer of its presence, Heads is intended for the case where you need to store data and state on the computer.

Research

• HEADS OS
• https://osresearch.net/
• https://github.com/osresearch/heads
• https://tech.michaelaltfield.net/2023/02/16/evil-maid-heads-pureboot/

Required checks

• This is not an opinion. It is fact. It is backed by [my own] research.
• I agree to the PSA Code of Conduct.

HEADS project is abandoned and unmaintained. for years. AFAIK?

This has been a request for a while now, and people from other organizations have recommended I place a Heads flashing guide in the main guide. It will be short but informative. Heads is not dead, imo. Just sleeping.
