Using a x86 linux machine and a USB CF Reader.

== 1. mount voyage CF and backup everything ==
<code>
mount /dev/sdb1 /mnt/uba
cd /mnt/uba
tar cvpzf /tmp/voyage-backup.tgz ./
cd /
umount /mnt/uba
</code>

== 2. mount larger CF, create partition ==
<code>fdisk /dev/sda</code>
  * create new partition, ext2 type linux
  * set bootable flag
  * write changes

== 3. make filesystem and apply label ==
<code>mkfs.ext2 /dev/sda1
tune2fs -i 0 -c 0 /dev/sda1 -L ROOT_FS
</code>

== 4. restore data ==
<code>
mount /dev/sda1 /mnt/uba
cd /mnt/uba
tar xvpzf /tmp/voyage-backup.tgz -C ./
</code>

== 5. setup grub again ==
//we are still in /mnt/uba//
<code>rm boot/grub/device.map
echo "(hd0) /dev/sda" > boot/grub/device.map</code>

//keep the / dev of current system before chroot//
<code>mount -o bind /dev /mnt/uba/dev</code>

//chroot and run grub//
<code>chroot /mnt/uba /usr/sbin/grub --device-map=/boot/grub/device.map</code>
> setup (hd0) (hd0,0)

> quit

<code>umount dev
cd ..
umount uba</code>

== 6. done! ==
