I don't think that this bug corresponds to your problem because you're bind-mounting "/dev". Does grub-probe work inside the chroot? grub-probe --target=abstraction / grub-probe --target=drive / grub-probe --target=fs / grub-probe --target=fs_uuid / grub-probe --target=partmap / -- To UNSUBSCRIBE, email to debian-user-requ...@lists.debian.org with a subject of "unsubscribe".
