VPS Re-install Debian Script

Now ready for Debian 10 (buster)!

Introduction

This script is used to re-install VPS to Debian 9 (stretch) or 10 (buster) with the official installer, but semi-automatically.

How It Works

1. Generate a preseed file to automate installation
2. Download Debian Installer to the boot directory
3. Alter GRUB2 configuration to boot the installer

Usage

sudo bash -c "$(wget -qO- https://github.com/brentybh/debian-netboot/raw/master/netboot.sh)" -- <OPTIONS>
