I'm pretty sure we can do that from d-i since that's needed to get UEFI support working AFAICT. Looking at udebs, it seems you want to be loading this one, probably manually if you're at an early stage: efi-modules-4.5.0-2-amd64-di_4.5.4-1_amd64.udeb It contains: ./lib/modules/4.5.0-2-amd64/kernel/drivers/firmware/efi/efivars.ko which is likely to make it possible to access efivars, allowing you to mount them on the mount point (which you mentioned, exists already). > If you answer, please add my e-mail address in CC because I'm not > subscribed to this list. Thank you very much. Done. KiBi.
