- This tool creates block device images compressed with xz.
- The images by default are shrunken and if the OS is systemd based, on first boot the disks will resize to the new sdcard size.
- The capture removes logs, apt archives, dhcp leases, ssh hostkeys and users bash history.
./capture-sdcard.sh <block device> <full path to image file with name>
A block device could be something like /dev/sdb.
Debian / Ubuntu
sudo apt install -y git xz-utils
./capture-sdcard.sh /dev/sdc /tmp/test-image.img
Using the block device /dev/sdc, capture a compressed image file to /tmp/test-image.img.xz.
