Would I be able to build this with a different payload?
Say for example I wanted the GRUB2 payload, so I went into config.librem15v3 and set “CONFIG_PAYLOAD_GRUB2=y”, then commented out anything relating to SeaBIOS. Would it build?
I don’t yet have the Librem 15 to test it out. Being able to get Coreboot with a disabled Intel ME and GRUB at the BIOS level, allowing for full-disk encryption including the /boot partition (like this), is a big factor in my decision to buy it in the next week or so.
