An opinionated script to initialize your Linux system.

This release has been tested on the following distributions, and should work on all distros based from:

• Arch
• CentOS
• Debian
• Fedora
• Ubuntu

Before running the installer, ensure you have:

• Sudo privileges on the machine

• Git identity configured globally:

  git config --global user.name "Your Name"
  git config --global user.email "you@example.com"

  or

  export GIT_USER_NAME="Your Name"
  export GIT_USER_EMAIL="you@example.com"

  Why: The installer passes your Git identity into the Ansible role and will fail if not provided. It will prompt if missing, but will exit if you leave either value blank.

• An SSH key present and loadable by ssh-agent:

  • Recommended to use ed25519 keys
  • Check for an existing key:

    ls ~/.ssh/id_ed25519 ~/.ssh/id_rsa

  • If you don't have one, generate a key:

    ssh-keygen -t ed25519 -C "your_email@example.com"

  • Add it to your agent (if needed):

    eval "$(ssh-agent -s)"
    ssh-add ~/.ssh/id_ed25519

  Why: The installer needs SSH access to clone private repositories. If no usable key is found, it exits with instructions to generate one.

Option 1: One-liner (audited remotely)

wget -O - https://raw.githubusercontent.com/kedwards/sysinit/refs/heads/main/install.sh | bash

or

curl -sSL https://raw.githubusercontent.com/kedwards/sysinit/refs/heads/main/install.sh | bash

Option 2: Clone locally, review, then run

git clone https://github.com/kedwards/sysinit.git
cd sysinit
./install.sh

Option 3: Run Ansible directly (manual, for advanced users)

The installer bootstraps tooling and a virtual environment for you; if you prefer, you can run the playbook directly:

• Ensure Python 3.11+ and dependencies are installed (uv/mise steps are handled by install.sh)
• Install dependencies:

  pip install -r requirements.txt
  ansible-galaxy install -r requirements.yml

• Run the playbook:

  ansible-playbook -i inventory/hosts.yml playbook.yml -K

This project uses Task for automation. After cloning:

# Install dependencies
task install-deps

# Install pre-commit hooks
task install-hooks

# See all available tasks
task --list-all

# Run linting
task lint

# Run tests
task molecule-test

Available Development Commands:

• task lint - Run all linters (pre-commit, ansible-lint, shellcheck)
• task syntax-check - Ansible syntax validation
• task molecule-test - Full Molecule test suite
• task molecule-converge - Quick converge for development
• task scan-secrets - Detect secrets in code
• task clean - Remove build artifacts

Notes:

• The installer will start an ssh-agent and attempt to load a default SSH key (id_ed25519, id_rsa). If none are found or loadable, it exits with guidance.
• The playbook targets localhost by default and will ask for sudo (-K) to perform system changes.
