System Health Audit

Status: Recommended

The 99-verify-install.sh script provides a high-fidelity audit of your MacBook Air 2020's configuration. It is designed to match the Iceunit professional aesthetic.

Audit Categories

1. Package Verification

Scans the local pacman database to ensure every required dependency from the 00-system-init phase is present and accounted for.

2. Service Health

Verifies the active status of critical background daemons:

• Thermal Control: Checks if mbpfan is actively managing your fans.
• Power Management: Confirms TLP is active and power-profiles-daemon is masked.
• Security: Ensures the UFW firewall is protecting your network.
• Containers: Validates that Docker or Podman is ready for dev work.

3. Hardware Optimisation

Inspects configuration files and the active kernel state:

• T2 Compatibility: Checks for intel_idle.max_cstate=4 and other critical T2 parameters.
• Sleep Mode: Confirms deep sleep is the default.
• Performance: Validates Ice Lake-specific sysctl tweaks.

4. Firmware & Storage

• BCM4377b: Ensures Wi-Fi and Bluetooth firmware files are in the correct directory.
• Code Vault: Checks for the existence of the LUKS2 image and confirms it is mounted at ~/Code.
