Dumping existing image

Install cockit on Raspberry Pi

sudo apt install cockpit

Shutdown Raspberry PI, take out the SD card, and connect it to your PC.

The boot- and rootfs-partitions were automatically mounted at the mentioned mount points. Before you proceed, unmount them with :

umount /dev/mmcblk0p1
umount /dev/mmcblk0p2

Now we copy the contents of the SD card to our file system.

sudo dd if=/dev/mmcblk0 of=/home/alang/worktmp/PiShrink/my_rasp.v2.img bs=32M

Download the PiShrink
