debinstaller-go

A Go-based Debian installer that supports both BIOS and EFI boot installations with LVM configuration.

Features

Support for both BIOS and EFI boot systems
LVM support
YAML-based configuration
Flexible partition configuration
Automated installation process
Support for both DHCP and static IP configuration

Prerequisites

Debian Live environment
Required Debian packages:
- gdisk: partition management with sgdisk command
- lvm2: LVM operations
- debootstrap: base system installation
- dosfstools: vfat filesystem operations with mkfs.vfat command
- arch-install-scripts: generating fstab with genfstab command

Installation

$ go build -o debinstaller-go ./cmd/debinstaller/main.go

Usage

Create a configuration file (see ./example for BIOS or EFI boot setup)
Run the installer with root privileges:

$ sudo ./debinstaller-go -config config.yaml

Configuration

The installer uses YAML configuration files. Two example configurations are provided:

config.yaml.bios: BIOS boot systems
config.yaml.efi: EFI boot systems

Storage Configuration

The storage section defines the partition layout and LVM configuration:

storage:
  devices:
    - /dev/sda
  bootloader:
    type: "bios"  # or "efi"
  partitions:
    - type: "bios_boot"      # For BIOS systems only
      size: "2M"
    - type: "efi_system"     # For EFI systems only
      size: "512M"
      filesystem: "vfat"
      mount_point: "/boot/efi"
    - type: "boot"
      size: "512M"
      filesystem: "ext2"
      mount_point: "/boot"
    - type: "lvm_pv"
      size: "15G"
      volume_group: "vg0"
      logical_volumes:
        - name: "root"
          size: "3G"
          filesystem: "ext4"
          mount_point: "/"
        - name: "home"
          size: "1G"
          filesystem: "ext4"
          mount_point: "/home"
        - name: "var"
          size: "1G"
          filesystem: "ext4"
          mount_point: "/var"
