+At startup, @command{nginx} has not yet read its configuration file, so it
+uses a default file to log error messages. If it fails to load its
+configuration file, that is where error messages are logged. After the
+configuration file is loaded, the default error log file changes as per

+@file{/var/log/nginx/error.log}. The second location can be changed with the
+@var{log-directory} configuration option.
