This repository provides an initramfs overlay for Alpine Linux that enables headless bootstrapping on systems without keyboard or display. The primary mechanism is a self-contained shell script (`headless_bootstrap`) executed during early boot, which automatically configures networking (Ethernet, WiFi, USB gadget), starts a temporary SSH server with pre-generated keys, and optionally triggers an unattended installation script. It supports USB gadget mode, version checking with auto-update, and a variety of customization via external files. The architecture is a collection of carefully crafted OpenRC service files, shell scripts, and configuration examples, packaged as an `apkovl.tar.gz` overlay. This is not a typical application but a system utility designed to solve a specific provisioning problem: remotely installing Alpine Linux on headless devices.
