So to update the step-by-step by Maxoueb with the suggestions from Qole We are assuming you are using (as in: installed and working) Qole's Debian image (debian.img.ext2, that can be downloaded from here: http://qole.maemobox.org/easy-deb-ch....6-2_armel.deb ). 1 -------- First step: create a new partition/format your memory card. (easiest way: mount your card on a linux box, use GParted to resize/create the new ext2 partition) Put back the card in your device, boot it up. 2 -------- Mount the current Debian image: With this command (as root): Code: mount -o loop /path/to/currentimgfile /debian Mount the new formatted partition: Code: mount /dev/mmcblkxxx /opt 4 -------- Copy the whole content of /debian to your freshly formatted partition. In the present case: Code: cd /debian /home/user/img-install/tar cf - . | (cd /opt/; tar xvf -) 5 -------- Restart device 6 -------- Edit /home/user/.chroot (as root: "vi /home/user/.chroot" ). Note that "IMGFILE=/dev/mmcblk1p1" needs to be modified to meet your needs (ie. replace "mmcblk1p1" to the ext2 partition you created) # Sample config for chroot # Device or image containing Debian filesystem. # Default: first in /media/mmc[12]/debian*.img* IMGFILE=/dev/mmcblk1p1 # Filesystem used; must always be set when using a partition. # Default: from extension of IMGFILE, or ext2. IMGFS=ext2 # Mount point for Debian. # Default: /debian CHROOT=/debian # New /tmp dir size for printing / PDF creation # Default: 2M TMPSIZE=2M # Debian user to drop privileges # Default: user DEBUSER=user 7 -------- You can remove the debian.img.ext2, as it's no longer needed) 8 -------- Tap on the "Debian chroot" menu item. If everything went well, you should see it mount the Debian image from: /dev/mmcblk1p1 (or whatever partition you have chosen) I found that there was no need to edit the /sbin/debian only the chroot.
