- Download the 2026-09-15 Raspberry Pi OS trixie arm64 lite image.
- Trixie (and NetworkManager-based bookworm) ignore wpa_supplicant.conf on the boot
partition: write a NetworkManager profile there instead, and set the regulatory
domain on the kernel command line. The SSID is now asked for too.
- Use whichever loop device is free rather than a hard-coded /dev/loop42, mount into a
temporary directory, and unmount and detach on any exit. Resolve paths from the
script's own location, and refuse to overwrite an already customised image.
