Nasledujuci manual ukazuje ako vytvorit image sd karty a ako taky image namountovat pokial obsahuje viac particii.
Na vytvorenie image do suboru sa pouzije prikaz dd.
dd if=/dev/mmcblk0 of=/opt/sd_automat bs=10M
Na namountovanie konkretneho image je potrebne vediet na akom offsete sa particia nachadza. To sa da zistit cez:
piecka@piecka-NB:/tmp$ fdisk /opt/sd_automat
You will not be able to write the partition table.

Nastavenie cez losetup je nasledovne:
<code>
piecka@piecka-NB:/tmp$ sudo losetup /dev/loop0 /opt/sd_automat -o $((2048 * 512))
piecka@piecka-NB:/tmp$ sudo losetup /dev/loop1 /opt/sd_automat -o $((4882432 * 512))
piecka@piecka-NB:/tmp$ sudo losetup /dev/loop2 /opt/sd_automat -o $((5859328 * 512))
Samotne namountovanie potom:
piecka@piecka-NB:/tmp$ mkdir 2 piecka@piecka-NB:/tmp$ mkdir 3 piecka@piecka-NB:/tmp$ mkdir 4 piecka@piecka-NB:/tmp$ sudo mount /dev/loop0 /tmp/2 piecka@piecka-NB:/tmp$ sudo mount /dev/loop1 /tmp/3 piecka@piecka-NB:/tmp$ sudo mount /dev/loop2 /tmp/4
