archinstall_autoBash - automated installation of Arch Linux via a bash script

Bash script to automate Arch Linux installation

  • installation parameters are set in a separate configuration file
  • manual input required only for:
    • encryption confirmation and encryption password
    • selcting grafics card (needs testing / maybe manual conf)

Usage

Boot live system

  • boot live system from an installation medium

Clone the repository

  • clone the repository
    • git clone https://gitlab.com/sanmue/archinstall_autobash.git
  • change to the direcory of the cloned repository
    • cd archinstall_autobash

Configuration

  • customize the variables in 'archinstall_autoBash.config' according to your needs
    • vim archinstall_autoBash.config # use your preferred editor instead of 'vim'
    • these variables are used by the script to execute the installation

Start installation of Arch Linux as configured

  • start the initial script in the cloned git repo folder
    • ./archinstall_autoBash.sh
      • remember to make the script files executable first, or simply all files in the folder: chmod +x *
  • after reboot:
    • login as a user with sudo privileges
    • clone the repo again and cd into it (for instructions: see further above)
    • execute the script: ./archinstall_autoBash_afterReboot.sh (as a user with sudo privileges)
      • installs 'snapper-rollback' (default=true, set/change via config)
      • bootable live system on ESP (e.g. for system rescue) (default, set/change via config)
        • Archiso on ESP and Grml on ESP and SystemRescue on ESP currently supported
        • only if bootloader is systemd-boot
        • requires manual download of installation iso to 'Downloads' folder of your currently logged in user before
        • if the script can not find the installation iso in the 'Downloads' folder, this step will be skipped (after iso download you can execute the script again)

Features

  • Bootloader: GRUB and systemd-boot
    • systemd-boot for UEFI boot mode and GRUB Bootloader for Bios boot mode (default, set/change via config)
  • UEFI or BIOS (detected automatically) with GPT
    • for BIOS / MBR: set MBR manually in config
  • Encryption
    • GRUB: keyfile to automatically decrypt root partition (default, optional, set/change via config)
  • Btrfs filesystem with subvolumes (flat layout, set/change via config)
  • Partitioning + formating of the disk (optional, set/change via config)
  • Swap: partition, file or none (set via config, current default: none)
  • 'zram': usage as swap (default, set/change via config)
  • Snapper snapshots for root subvolume (optional, set/change via config)
    • only if btrfs filesystem is specified and snapper set to 'true' in config
  • Grafics cards drivers (optional, set/change via config)
    • detected automatically, no 32bit application support, needs testing
    • AMD: should work (works on my machine ;-))
    • Intel: needs manual config, not testet, see Arch Wiki for current info
    • NVIDIA: needs manual config, not testet, see Arch Wiki for current info
  • Desktop Environment (default: Gnome, or none; set/change via config)
    • with additional packages: Firefox (and spice-vdagent if VM) (set/change via config)
  • Virtualization support (QEMU/KVM) (default: false (no install), optional, set/change via config)
  • Post-install (after reboot):
    • snapper-rollback (AUR) for simple rollback to a desired snapshot (default: true (install), optional, set/change via config)
      • only in combination with btrfs filesystem and snapper
  • bootable live system on ESP (e.g. for system rescue)
    • Archiso on ESP and Grml on ESP and SystemRescue on ESP currently supported (default, optional, set/change via config)
    • only if bootloader is systemd-boot
    • requires manual download of installation iso to 'Downloads' folder
    • if the script can not find the installation iso in the 'Downloads' folder, this step will be skipped
    • after iso download you can execute the "after boot"-script again

Limitations

  • no seperate 'home' partition
  • only Gnome Desktop Environment or no DE (optional via config)
  • no multi-boot
  • no LVM or RAID
  • if opted for virtualization: no nested virtualization configured
  • btrfs filesystemt is set by default. If you set to another filesystem in the config: not tested
