OK, the upstream code is setting TZLOAD_FROMENV unconditionally even when not using the environment variable. That is causing us to consider /etc/localtime as untrusted, and then reject it because it is not relative to /usr/share/zoneinfo. Unfortunately this fell between the cracks of my test cases (it's a combination of the thin_jail and setugid cases). I'll submit a patch upstream and fix it locally.
