Debian Network Reinstall Script

Introduction

This script is used to reinstall the Linux OS of a KVM-based VPS or a Hyper-V virtual machine to Debian 10 Buster.

How It Works

  1. Generate a preseed file to automate installation
  2. Download the 'Debian-Installer' to the /boot directory
  3. Append a menu entry of the installer to the GRUB2 configuration file

Usage

sudo bash -c "$(curl -fsSL https://github.com/bohanyang/debi/raw/master/debi.sh)" -- <OPTIONS>
