Now that I have GuixSD installed on that machine I don’t have /sys/firmware/efi at all. /sys/firmware contains “acpi”, “dmi”, and “memmap” only. The problem occurred when I tried to install GuixSD (after booting from a GuixSD installer USB drive), not when reconfiguring. I don’t have a USB drive with me at the moment, so I cannot check the contents of /sys/firmware in the installer GuixSD now. -- Ricardo GPG: BCA6 89B6 3655 3801 C3C6 2150 197A 5888 235F ACAC https://elephly.net
