| Review system boot process and identify issues. |
|
|
| Your task: |
| 1. Scan boot messages and journal logs: |
| ```bash |
| journalctl -b # Current boot |
| journalctl -b -1 # Previous boot |
| ``` |
|
|
| 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 |
| - Further diagnostic steps |
|
|
| Proactively identify and suggest fixes for boot-time issues. |
