      Base system is ready! Next step: Run the bootstrap script.

      Run this command to set up dotfiles:

          bash -c "$(curl -fsSL https://xxz.dk/l/u24b)"

      This will:
        • Install GitHub CLI and Bitwarden (desktop + CLI)
        • Authenticate with GitHub (browser login)
        • Clone your private dotfiles repo
        • Run the full setup automatically

      Note: Open Bitwarden desktop app and login to access passwords!

      After bootstrap completes, remove this message:
          sudo rm /etc/update-motd.d/99-post-install

      MOTD
      EOF'
    - curtin in-target --target=/target -- chmod +x /etc/update-motd.d/99-post-install

  # Automatic reboot after installation
  shutdown: reboot
