Program narrative

This course keeps drills close to support tickets you already see: stuck services, masked units, and rescue targets. You work on isolated lab VMs with deliberate faults, document each fix in a short runbook entry, and compare notes with mentors who still carry a pager rotation.

What the labs include

Unit file anatomy lab with overrides and drop-ins
journalctl filters mapped to common outage signatures
cgroup hints when a service silently thrashes
socket activation patterns for on-demand daemons
Graceful degradation exercise with dependency loops
Pair rotation on triage scripts you can reuse Monday
Checklist for handoffs to the next shift

Outcomes you can show a lead

Document a restart path that survives audit review
Predict whether a failure is config, disk, or dependency
Ship a two-page runbook your desk neighbor can follow cold

Straight FAQ

Do I need root on my employer laptop?

No. Labs run in our cloud sandbox. We only ask that you can SSH with keys we issue.

Is certification included?

We focus on repeatable workflows, not exam cramming. Exam vouchers are not part of tuition.

What is intentionally left out?

Kernel rebuilds and driver debugging are out of scope so we can go deep on user-space services.

Recent participant notes

“The dependency-loop lab mirrored a ticket I fought for weeks. Finally someone drew the graph on paper first.”

“journalctl filters alone were worth it. I keep the printed cheat sheet taped inside my locker.”
