Based on @craftyguy 's #osk-sdl work i added cryptsetup-initramfs support to the #librem5's image-builder so one can build #luks encrypted images too. There's more work needed for this to hit the factory floor but at least one can build own images with encryption once all is merged. The video shows the devkit since this a bit simpler to debug over serial:
@agx I typically install Debian through a live image, but I'm guessing no live image will be quite right for the L5 yet. So all of the partitioning, fstab/crypttab, etc needs to be set up at image build?
