There is a common misconception that full means "everything." In reality, this tarball is approximately 1.2GB to 1.8GB compressed and expands to ~4GB–6GB. While it includes the top 200 Kali tools, you will still need to run apt install kali-linux-large if you want absolutely every package. The full label distinguishes it from the minimal (500MB) and nano (console-only) variants.
apt update apt install -y u-boot-rpi arm64-efi kalifsarm64install fulltarxz
The official pre-built images force a specific partition layout (usually a Fat32 /boot and ext4 /). With the fulltarxz method, you manually create the partitions, allowing you to use ZFS, F2FS (for cheap SD cards), or LUKS encryption from the start. There is a common misconception that full means
sudo chroot /mnt /bin/bash
Mount your target partition and extract the fulltarxz. The -xpf flags are crucial: you manually create the partitions
sudo mount /dev/sdX2 /mnt/kali_root
sudo tar -xpf kalifs-arm64-full.tar.xz -C /mnt/kali_root
