Spend longer whenever you need.</p><p>A server OS combines a kernel with boot and service management, storage, networking, accounts, updates, and recovery. Building a server distribution is different from writing a new kernel. Choose which goal your project has. Draw the request path from a network interface through a service to storage, and mark every trust boundary.</p><p><strong>Practice and evidence:</strong> Predict the example or draw its state transitions. Change one assumption, test the boundary, and record the actual result. Explain what this small model does not establish about a production system.</p><h3>Practice and evidence</h3><p>Keep three notes: your prediction, the actual result, and why they match or differ. The completion check grades understanding; the practice task builds skill.</p></html> |
