After updating world topday, my system didn't restart. Somehow, the new gawk links against libexpat, whereas the old one didn't do that. My /usr isn't on the same partition as / and so, the shared file can't be loaded. The system doesn't get far. Reproducible: Always Steps to Reproduce: 1. Emerge gawk 2. reboot Actual Results: Kernel loads fine and then ... nothing. Expected Results: Go on booting.
