+    "reboot": { "unassisted": false }
+  },

+}
+
+Packages listed in `ignore` sections are substring matched. Pre-10.10 machines will need to run this
+script with `sudo` even if the user can use sudo without a password. This script should be safe to run
+from cron - it only produces output if something happens.
