Infrastructure Baseline Verification

Overview

On February 27, 2026, the initial infrastructure baseline for the mw-pfeddersheim-workstation was successfully applied and verified. This process ensured that the workstation adheres to the saTway standards and is ready for higher-level configurations.

Verification Results

1. Ansible Playbook Execution

The ansible/workstation.yml playbook was executed first in --check mode and then applied.

• Status: Success
• Key Changes:
  • Optimized kernel parameters (swappiness, inotify, cache_pressure).
  • Configured logind for faster user transitions.
  • Installed core dev tools (ripgrep, fd, jq, etc.).
  • Cleaned up legacy VS Code remnants and local AI artifacts.
  • Verified system maintenance tasks (package cache and journal vacuuming).

2. Maintenance Script (scripts/maintenance.sh)

The enhanced maintenance script (v1.1.0) was used to perform deep cleaning and health checks.

• Status: Success
• Actions Performed:
  • Checked for system updates (clean).
  • Vacuumed systemd journal logs.
  • Pruned Arch package cache.
  • Removed 15 orphaned packages (Total Removed Size: 387.50 MiB), including legacy headers and obsolete tools.
  • Pruned Docker system data and volumes.
  • Pruned pnpm global store (Removed 856 files).
  • Verified repository status (clean on feat/initial-baseline).

Technical Improvements

• Non-destructive Check Mode: The maintenance script now supports --check, allowing for safe audits.
• Robust Error Handling: Resolved issues with checkupdates exit codes and permission requirements for cache size calculations.
• Conflict Resolution: Successfully handled code-marketplace conflicts during tool management.

Baseline State

The workstation is now in a stable, clean state with a documented baseline. Disk usage is optimized (76% utilized), and all core automation tools are functional.

Next Steps

• Finalize the feat/initial-baseline branch and merge if applicable.
• Proceed with dotfiles management and advanced developer environment setup.
