When I enter # update-grub I get an error message: /usr/sbin/grub-probe: error: cannot find a device for / (is /dev mounted?).
/dev has been mounted before entering the chroot /mnt environment using # mount --rbind /dev /mnt/dev If I enter # grub-probe it answers: No path or device is specified. If I enter # grub-probe /boot it answers: zfs So, what do I need to do to make update-grub work?
