+     utmps does not support changing the utmp file: this file is
+    hardcoded as $wd/utmp, $wd being the working directory of
+    the utmps-utmpd daemon.
+
+     Software that needs to change the utmp file should instead
+    run its own instance of utmps-utmpd to access the alternate
+    file the software wants, and connect to that instance.
+
+     A stub is still provided so software can *build* and work
+    in the cases where it doesn't try accessing a non-default
+    utmp file.
