# Debian Network Reinstall Script |
|
|
|
## Introduction |
|
|
|
This script is written to reinstall a VPS/virtual machine to Debian 10 Buster. |
|
|
|
## Should Work On |
|
|
|
### Virtualization Platform |
|
|
|
* SolusVM/OpenStack/DigitalOcean/Vultr/Linode/Proxmox/QEMU KVM (BIOS boot) |
|
* Oracle Cloud Infrastructure (with `--force-efi-extra-removable`; UEFI boot) |
|
* Google Cloud Compute Engine (manually set the VPC internal `--ip`, `--netmask`, `--gateway`; UEFI boot) |
|
* AWS EC2 & Lightsail (BIOS boot) |
|
* Hyper-V **but not Azure!** (Generation 1 BIOS boot & Generation 2 UEFI boot) |
|
|
|
### Original OS |
|
|
|
* Debian 8/9/10 |
|
* Ubuntu 14.04/16.04/18.04/20.04 |
|
* CentOS 7/8 |
|
|
|
## 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 |
|
|
|
curl -fLO https://raw.githubusercontent.com/bohanyang/debi/master/debi.sh && sudo bash debi.sh <OPTIONS> |
|
|

|
* `--mirror-host deb.debian.org` |

|
* `--skip-account-setup` |
|
* `--username debian` New user with `sudo` privilege or `root` |
|
* `--password <string>` New user password to set. **Will be prompted if not specified here** |

|
* `--no-force-gpt` By default, GPT rather than MBR partition table will be created. This option disables it. |
|
* `--bios` Don't create *EFI system partition*. If GPT is being used, create a *BIOS boot partition* (`bios_grub` partition). Default if `/sys/firmware/efi` is absent. [See](https://askubuntu.com/a/501360) |
|
* `--efi` Create an *EFI system partition*. Default if `/sys/firmware/efi` exists |

|
* `--architecture <string>` e.g. `amd64`, `i386`, `arm64`, `armhf`, etc. |
|
* `--boot-partition` Should be used if `/boot` directory is mounted from a dedicated partition like a LVM setup |
|
* `--firmware` Load additional [non-free firmwares](https://wiki.debian.org/Firmware#Firmware_during_the_installation) |
|
* `--force-efi-extra-removable` [See](https://wiki.debian.org/UEFI#Force_grub-efi_installation_to_the_removable_media_path). **Useful on Oracle Cloud** |
