Armbian Iso — Must Watch

output/images/Armbian_24.11.0_Orangepi5_noble_current_6.1.75_minimal.img.xz : ✅ Checksummed (SHA256) ✅ Verified boot (u-boot + signed FIT image if enabled) ✅ Production packages (no dev leftovers) ✅ Can be flashed with balenaEtcher / dd 6. If you truly need .iso for ARM (non‑standard) You can wrap the .img into a hybrid ISO for some UEFI ARM64 systems:

chmod +x userpatches/customize-image.sh After build: armbian iso

#!/bin/bash # Runs inside chroot during build apt update apt install -y docker.io fail2ban ufw useradd -m -s /bin/bash myuser echo "myuser:securepassword" | chpasswd Make it executable: output/images/Armbian_24
