Hello, I'm trying to install GuixSD on a USB SSD drive. I downloaded: [ https://ftp.gnu.org/gnu/guix/guix-system-install-1.1.0.x86_64-linux.iso.xz.sig](https://ftp.gnu.org/gnu/guix/guix-system-install-1.1.0.x86_64-linux.iso.xz.sig)
Then: $ sudo dd if=guix-system-install-1.1.0.x86_64-linux.iso of=/dev/sde Where `/dev/sde' is a usb drive to boot from. I connected the USB boot drive and the USB SSD drive where to install GuixSD, followed the guided install wizard and ended with this error: guix system: error: '/gnu/store/...grub-efi-2.04/sbin/grub-install --boot-directory /mnt/boot --bootloader-id=Guix --efi-directory /boot/efi' exited with status 1; output follows: grub-install: error: failed to get canonical path of ` /boot/efi' How to install GuixSD? Thanks, phf
