A script for running on a live Linux distribution (such as Alpine), in order to install a custom Debian-based system onto your computer's hard drive of choice.
install.sh configures your host system. setup-debian.sh installs your custom distro.
From Alpine Linux, simply add install.sh to your /etc/profile, and it will run automatically on boot.
