Installing OpenBSD with full disk encryption
--------------------------------------------
Not working. You can modify the above procedure (installation w/o
encryption) to install OpenBSD using full disk encryption, and it
appears to work, except that it's not yet clear how to actually *boot* an
OpenBSD+FDE installation using Libreboot+Grub2. If you get it working,
please let us know.
If booting in text mode (framebuffer mode might also work), it might be
possible to chainload the OpenBSD or LibertyBSD bootloader from the MBR
section on the internal storage device. This way, it would be possible
to boot with an encrypted OpenBSD or LibertyBSD installation. Please let
us know (contact details are on the Libreboot homepage) if you get it
working this way.
If you are using SeaBIOS, OpenBSD's bootloader will be
chainloaded automatically and everything will just work.
Alternatively, it would be good to port OpenBSD either natively as a
coreboot payload, or port it to libpayload (payload library in coreboot;
it has a basic C library and a few functions for certain operations e.g.
text/bitmap). *This would be ideal, because then it would be possible
to boot a truly fully encrypted OpenBSD or LibertyBSD installation, by
putting everything in the flash chip.*
Alternatively, modifying GRUB to support booting fully encrypted OpenBSD
installations would be possible, but probably not feasible; it's an
alien codebase to the OpenBSD project, not tightly integrated and the
OpenBSD bootloader already works.
