Unable to build with GRUB (i386, iso image)

[Miguel Villanueva Lobato <miguel.villanueva.lobato@gmail.com>]

Hi,

I'm using live-build version 2.0.12-2 in Debian GNU/Linux 6.0.3 (squeeze)

with auto/config

#!/bin/sh
lb config noauto \
        -a i386 \
        -b iso \
        --bootloader grub \
        --hostname liveDebian \
        --username miguel \
        --bootappend-live "persistent locales=es_ES.UTF-8 keyboard-layouts=es" \
        "${@}"
echo "ejecutado script config noauto"

While building, the error message bellow appears. The iso image is not
being generated:
(At the same time It's being showed the warning message that I
explained in the mail before with subject: "df: Warning: cannot read
table of mounted file systems: No such file or directory")

Creating config file /etc/default/grub with new version
grub-probe: error: cannot find a device for / (is /dev mounted?).
grub-probe: error: cannot find a device for /boot (is /dev mounted?).
