Please specify --target or --directory.This is strange. When you reconfigure, Guix should print the grub-install command that was used, which should include both --target and --directory.
The full message is:guix system: error: '/gnu/store/v77n5m....grub-efi-2.06/sbin/grub-install --boot-directory //boot --bootloader-id=Guix --efi-directory=/boot/efi' exited with status 1; output follows:
/gnu/store/.../grub-install: error: /gnu/store/.../lib/grub/i386-pc/modinfo.sh doesn't exist. Please specify --target or --directory'
Note that the grub-install command doens't contain '--target' or '--directory'. (Also: my system is x64, and this seems to be for i386. Should there be a --target=x64_86-efi somewhere?)
However, perhaps the chroot is at fault: Before chrooting to, let’s say, /mnt with chroot /mnt, you need to have mounted the /dev/sdXy file system with EFI on it (that which is declared in your config.scm) to /mnt/boot/efi.
I have in my config 'target /boot/efi'. My EFI partition is /dev/sda1. If I mount it like
# mount /dev/sda1 /mnt2 (/mnt2 because I already have my /dev/sda3 partition with guix at /mnt) I find the following layout: /mnt2/EFI/ EFI grub Guix what would be the correct bind mount? I tried # mount --bind /mnt2/EFI /boot/efi so I now have /boot/efi/ EFI grub Guix Any idea if that is the desired layout? thanks! Thomas
