I've tried and install the contents of the
freedombox-unstable_2012.1021_dreamplug-armel-card.img image to a 4GB SD
card, which was previously partitioned.

I've tried using kpartx to locally mount the contents of the immage
without success :

$ sudo kpartx -l freedombox-unstable_2012.1021_dreamplug-armel-card.img
loop0p1 : 0 262144 /dev/loop0 2048
loop0p2 : 0 3833856 /dev/loop0 264192
loop deleted : /dev/loop0

$ sudo kpartx -a freedombox-unstable_2012.1021_dreamplug-armel-card.img
device-mapper: resume ioctl on loop0p2 failed: Invalid argument
create/reload failed on loop0p2

:-(

FYI, 
$ sudo fdisk -lu freedombox-unstable_2012.1021_dreamplug-armel-card.img

Disk freedombox-unstable_2012.1021_dreamplug-armel-card.img: 1992 MB, 1992294400 bytes

Maybe this is because kpartx doesn't know how to proceed with a first
partition not starting at sector 1.

Anyway, using losetup, I managed to make the partition 2 mounted :
# losetup /dev/loop0 freedombox-unstable_2012.1021_dreamplug-armel-card.img -o $((264192 * 512))
# mount /dev/loop0 /mnt/freedom

However, some files can't be copied when I try to rsync to the SD card's
partition :
# rsync -atvz --progress --delete --exclude=boot /mnt/freedom/ /mnt/freedom2/
sending incremental file list
rsync: readlink_stat("/mnt/freedom/usr/share/perl/5.14.2/CPANPLUS/Backend") failed: Input/output error (5)

Have any others had better results ?

Thanks in advance.
