Cockpit should help someone diagnose why a machine unexpectedly went down.

1. Unclean shutdown happens (system crash, intentional power cycle, power outage, etc.)
2. Computer boots
3. User logs into Cockpit
4. Cockpit shows that the computer was shutdown unexpectedly
5. Cockpit provides a way to figure out what happened

My initial thought would be to:

• add a notice about the unexpected shutdown
• provide a link to the logs page that shows the previous system boot, sorted with the last entries at the top

While this wouldn't outright solve the problem, it would be a good way to at least let someone know that the system crashed and provide a minimal possible way to start debugging the issue.
