| Review system boot process and identify issues. | |
| Your task: | |
| 1. Scan boot messages and journal logs: | |

| 2. Identify issues: | |
| - Failed services | |
| - Error messages | |
| - Warnings | |
| - Slow-starting services | |
| - Dependency problems | |
| 3. Analyze boot performance: | |
| ```bash | |
| systemd-analyze # Overall boot time | |
| systemd-analyze blame # Time per service | |
| systemd-analyze critical-chain # Critical path | |
| ``` | |
| 4. Suggest remediation: | |
| - Fix failed services | |
| - Disable unnecessary services | |
| - Resolve dependency issues | |
| - Optimize slow services | |
| 5. Provide actionable recommendations: | |
| - Commands to investigate specific issues | |
| - Configuration changes needed | |
| - Services to disable or reconfigure | |
